Rich deposited money into a bank account that earned 2.5% simple interest each year. After 2 years, he had earned $14.65 in interest on the account. If no other money was deposited into or withdrawn from the account, how much was his initial deposit?

Answers

The formula for simple interest is
[tex]I=Prt[/tex]
where I=interest earned, P=initial deposit, r=rate of increase, and t=time.

We have
[tex]I=14.65[/tex]
[tex]r=2.5\%=0.025[/tex]
[tex]t=2[/tex]

Plug in:
[tex]14.65=P(0.025)(2)[/tex]
Solve for [tex]P[/tex]:
[tex]14.65=0.05P[/tex]
[tex]\rightarrow P=293[/tex]

So the initial deposit was $293.

Answer:

the answer is 293

Admission to a car show costs $5 for each ticket. After selling only 20 tickets, they decided to lower the price to $3 each. If they raise $217 ,how many tickets did they sell in all?

Answers

First you would multiple 5 × 20 which equals $100 then you would subtract $217 by $100 and you would get 39 tickets and then you would add your twenties tickets and your 39 tickets together to get your answer which is 59 tickets.

First you do 5x20=100 then you need to find out what is the closes thing to 217 so you do 3x40=120 then you subtract 3 from 120 to get 117. Then you take that 20 pictures and the 39 from the 40 then subtracting 1 then do 20+39=59. Which means they sold 59 tickets

Eric downloads a 10% off any one item coupon and goes shopping at Gadgets Galore, where he buys a digital camera for $93 and an extra battery for $13.99.

Answers

I assume the question is asking how much he paid...?

If so, he has 10% off from 100% of the original price.
100% - 10% means he will pay 90% of the original price.
To find the original price we must add the price of the two items together to get the total price.

$93 + $13.99 = (I will let you do the math.)

Then we must multiply the total price by the percentage he paid (90%).
To do this we must convert 90% into a decimal.
Percent(%) is just a way of saying "Out of 100".
So 90/100 = .90

For the final answer multiply: .90 * total price = answer.

Jackie wants to buy a new CD player. It costs $32.95. She has saved $26 and has a new coupon for %30 off the price. Does Jackie have enough money to buy the CD player?

Answers

32.95*.3 = 9.9 off original price
32.95-9.90=23.05

is 23.05< 26

yes

Answer:

The correct answer is Yes, she has enough money to buy the CD player.

Step-by-step explanation:

First we must analyze the information we have:

We know that Jackie has saved $ 26 to buy a CD that costs $ 32.95.

In principle we could say that she does not have enough money. But she has a 30% discount coupon.

Now we must find out if with that she will have enough money to pay for the CD.

For that we must know how much money she got off.

And we will do it as follows:

Discount coupon: 32, 95. 0.30

Discount coupon: 9.88

Now we know that the total CD was discounted $ 9.88.

We just have to do the subtraction:

32.95 - 9.88 = 23.07

Therefore, we can say that Jackie will have enough money to buy the CD player.

[tex]x-y=3[/tex]
[tex]x+2y=-6[/tex]

Subtract both equations to isolate and solve for y.

[tex](x-x)+(-y-2y)=3-(-6)[/tex]
[tex]0+-3y=9[/tex]
[tex]y=-3[/tex]

Now, solve for x in either equation by plugging in the y value.
I will choose the simpler first equation: [tex]x-y=3[/tex]

[tex]x+3=3[/tex]
[tex]x=0 ; y=-3[/tex]

x - y = 3 >> x = 3 + y
substituting this x in the second equation gives us
3 + y + 2y = -6 >> 3y = -9 >> y = -3
substituting this value of y in x = 3 + y gives us:
x = 3 + (-3) = 3 - 3 = 0

so the solution is: y = -3 and x = 0
