gene paid a deposit on a leased car. the deposit earns 2.8 percent simple annual interest. at the end of the year, the interest that is earned is $22.40. what was the amount of the original deposit?
a. $0.63
b. $80.00
c. $62.72
d. $800.00

The formula for simple interest is I = prt

P = Principal, meaning the starting amount of money, or in this case your deposit.

R = Is the interest rate (percent) in decimal form, only problem is you didn't include this.

T = Time money is gaining interest. ALWAYS IN YEARS!

To find the P, we will have to substitute the choices in to see which works.

R = 2.8% which becomes 0.028

T = 1

So, if we insert the first choice into the equation, it looks like this:

I = (0.63)(0.028)(1)

After you multiply those together, you get

.01764

Next choice,

I = (80)(0.028)(1)

You get 2.24, which is close, but not quite.

Next choice,

I = (62.72)(0.028)(1)

You get 1.75616

Last choice,

I = (800)(0.028)(1)

You get 22.4

So, your answer is D. $800.00

Hope this helps!

the answer is 800! You just do the math and that should be your answer!

Step-by-step explanation:

hey there!

if she's saving for six months, let's divide the total number we need for the trip by six, dividing it into the amount that needs to be saved for each month.

500 ÷ 6 =

she needs to save at least this amount each month, so we should use this symbol: ≥

let x be the amount she saves each month.

your final answer is x ≥

hope this !

r(0,90)(x,y) . t(-5,0)

last option

step-by-step explanation:

∆def to ∆d"e"f"

- rotate 90 counterclockwise degrees

- then translated 5 to the left (x --> x - 5)

answer is the last option
