A certain TV can be purchased from the manufacturer for $160. A certain online retailer has a standard markup of 30%, and a certain superstore has a standard markup of 40%.

(a) What is the price of the TV when purchased online? What is the price of the TV when purchased at the superstore?
(b) What is the difference between the prices in Part (a)? How does this relate to the difference in the markup?

Answers

(a)

Answer:

The price of the TV purchased online is $208

The price of the TV purchased at the superstore is $224

Explanation

To solve this, we are going to use the markup formula solved for price:

[tex]Price=markup*cost+cost[/tex]

where

[tex]markup[/tex] is expressed in decimal form

- For the online retailer:

We know that the the TV can be purchased from the manufacturer for $160, so [tex]cost=160[/tex]. We also know that its markup is 30%; to express the markup as a decimal, we just need to divide it by 100%, so [tex]markup=\frac{30}{100} =0.3[/tex]. Now we can replace the values in our formula to find the price of the TV at the online retailer:

[tex]Price=markup*cost+cost[/tex]

[tex]Price=0.3*160+160[/tex]

[tex]Price=48+160[/tex]

[tex]Price=208[/tex]

The price of the TV purchased online is $208

- For the superstore:

The cost is the same, so [tex]cost=160[/tex]. The markup this time is 40%, so [tex]markup=\frac{40}{100}=0.4[/tex]. Let's replace the values to find the price:

[tex]Price=0.4*160+160[/tex]

[tex]Price=64+160[/tex]

[tex]Price=224[/tex]

The price of the TV purchased at the superstore is $224

(b)

Answer

The difference between the prices is $16

The difference relates to the markup in two ways:

- When the markup increases 10% (from 30% to 40%), the price of the TV increases by $16.

- When the markup increases 10% (from 30% to 40%), the price of the TV increases 7.7%.

Explanation

To find the difference of our prices, we just need to subtract the price of the TV purchased at the superstore from the price of the TV purchased online:

$224 - $208 = $16

Now, to find how much the cost increased when the markup increases from 30% to 40%, we are going to divide the result of the difference of the two prices by the price of the TV at the online retailer, and then multiply by 100%:

[tex]\frac{16}{208} *100=7.69[/tex]

Which rounds to 7.7%

We can conclude that when the markup increases 10% (from 30% to 40%), the price of the TV increases 7.7%.

We can also conclude that when the markup increases 10% (from 30% to 40%), the price of the TV increases by $16.


Answer:

a) The price online of the TV is 208$

And in the superstore, it is 224$

b) The difference between the prices is $16.

208 - 224 = 16

The market difference is related as follows:

When the markup increases by 10% (from 30% to 40%), the price of the TV increases by $16.

What does x equal? 3(14x-15)=-72

Answers

-.642 is the correct answer in pretty sure.....
The 3(14x-15) is basically multiplying so 3*14x-3*15 so that would be 42x-45=-72. After that, you add 45 on both sides canceling -45 and make the -72 to -27. 42x=-27, now you divide 42 into both sides making x=-27/45.

The ordered pairs (1, 16), (2, 25), (3, 36), (4, 49), and (5, 64) represent a function. What is a rule that represents this function?
Also, how do I know how to find the rules of functions?

Answers

I know this question is like a year old but here is the answer
y = (x+3)^2


Answer:

The rule representing the function is [tex]f(x)=(x+3)^2[/tex].

Step-by-step explanation:

We are given,

The ordered pairs for the function are (1, 16), (2, 25), (3, 36), (4, 49), and (5, 64).

It is required to find the rule representing the function.

Now, we see that,

[tex]16=(1+3)^2[/tex]

[tex]25=(2+3)^2[/tex]

[tex]36=(3+3)^2[/tex]

[tex]49=(4+3)^2[/tex]

[tex]64=(5+3)^2[/tex]

From the pattern,we get the function is [tex]f(x)=(x+3)^2[/tex].

Hence, the rule representing the function is [tex]f(x)=(x+3)^2[/tex].

Answers

OK, so I think you divide 30 by 310 which would be... 1 R 10  or fraction one and one-third 1 1/3
Does this help?

Answer:

93 students

Step-by-step explanation:

We need to calculate the 30% of 310 students.

We can calculate with a direct rule of 3. If the 100% is 310 students, how many students are the 30%?

[tex]100 -\!\!\!-\!\!\!- \text{310 students}\\ 30 -\!\!\!-\!\!\!- \text{x students}[/tex]

We use the formula of the direct rule of 3:

[tex]x = \frac {30 * 310}{100} \\ \\ x = \frac {9,300}{100}\\[/tex]

x = 93

Dominic, Ralf and Peter have just eaten a HUGE Christmas meal. Dominic now weighs half as much as Ralf, and Peter weighs three times as much as Dominic. Together they weigh 720 pounds. How much does Dominic weigh?

Answers

 Answer 120 pounds

WORKINGS

Let Dominic’s weight be represented by ‘D’
Let Ralf’s weight be represented by ‘R’
Let Peter’s weight be represented by ‘P’

Given,
Dominic now weighs half as much as Ralf;
D = ½ R
R = 2D                ….. (Equation I)

Peter weighs three times as much as Dominic;
P = 3D                ….. (Equation II)

Together they weigh 720 pounds
D + R + P = 720 pounds                ….. (Equation III)


How much does Dominic weigh?
D is unknown?



Substitute equation I (R = 2D) for the value of R in equation III
D + R + P = 720 pounds                ….. (Equation III)
D + 2D + P = 720 pounds
3D + P = 720 pounds                ….. (Equation IV)

Substitute equation II (P = 3D) for the value of P in equation IV
3D + P = 720 pounds                ….. (Equation IV)
3D + 3D = 720 pounds
6D = 720 pounds
D = 720/6 pounds
D = 120 pounds

Therefore, Dominic weighs 120 pounds.

(b) What is a good interval to use for the y-axis? Explain your reasoning.

Answers

A. Probably about 10 dollars. Around 7 intervals is going to be enough to see the difference.
B. Months. 12 points on the y axis is more then enough to make a graph. 

If my answer helped, please mark it is "the brainliest answer" 
Thanks
-j

Answer:

A. $10

B. 12 points

Step-by-step explanation:

Let, the x-axis represents the number of months and y-axis represents the money for the grocery.

Now, as we have the range of the grocery bills from $110 to $170.

Thus, taking the scale of $10 on y-axis will give us 7 intervals in which the changes in the grocery bills can be viewed.

Hence, a scale of $10 is a good scale.

Further, as y-axis represents the number of months. Thus, taking 12 months will be sufficient to plot the graph and show the changes in the grocery bills.

Hence, 12 points representing months are sufficient.

350 yards to 420 yards

Answers

70 yards hoping this helps

The range from 350 yards to 420 yards is of 70 yards.

To understand the range from 350 yards to 420 yards, it is important to recognize that this involves simple subtraction and addition within a specific interval. The interval is calculated as follows:

The lower limit: 350 yardsThe upper limit: 420 yards

The range between these two distances is:

Lower Limit: 350 yardsUpper Limit: 420 yards

To find the difference, which represents the span or range between these two points, simply subtract the smaller number from the larger number:

420 yards - 350 yards = 70 yards

Thus, the range between 350 yards and 420 yards is a total of 70 yards.

deshawn deposited $6500 into a bank account that earned 11.5percent simple interest each year . he earned $4485 in interest befour closing the account. if no money was deposited into or withdrawn from the account, for how many years was the money in the account round the answer to the nearest whole year

Answers

Final answer:

The money was in the account for 6 years.

Explanation:

To find the number of years the money was in the account, we can use the formula for simple interest: I = P * r * t, where I is the interest earned, P is the principal (initial amount), r is the interest rate, and t is the time in years. We are given that Deshawn earned $4485 in interest and the interest rate is 11.5%. Let's plug in these values and solve for t:



4485 = 6500 * 0.115 * t



Simplifying the equation gives us:



t = 4485 / (6500 * 0.115) ≈ 6.1337



Rounding to the nearest whole year, we can conclude that the money was in the account for 6 years.

which is a solution of the inequality y < x - 8

Answers

Final answer:

A solution to the inequality 'y < x - 8' is any point where the y-value is less than the x-value minus 8. An example solution is the point (10, 1). To find all solutions, one would graph the boundary line y = x - 8 and shade the region below it, without including the line itself.

Explanation:

The question 'which is a solution of the inequality y < x - 8' falls within the subject of Mathematics, specifically under the topic of inequalities in algebra. A solution to this inequality is any ordered pair (x, y) where the y-value is less than the x-value minus 8. For example, if x is 10, then y must be less than 2 to satisfy the inequality, such as the point (10, 1).

To visualize this, you would graph the line y = x - 8 and then shade the region below this line on a coordinate plane. The shaded region represents all the points where the y-coordinate is less than the x-coordinate minus 8, thus showing all the potential solutions to the inequality. Points on the boundary line are not included since the inequality is strictly less than, not less than or equal to.
