100 dollars should be a one time fee so that has to be added to the equation, and since it is a one time fee it should not have a variable next to it.

It also says that you have to pay 720 dollars per month, so it has to have a variable next to it to show the number of months that she needs to pay that amount of money.

The answer should be D.

y= 720x +100

<h3>What is compound interest?</h3>

Compound interest is the amount charged on the principal amount and the accumulated interest with a fixed rate of interest for a time period.

The formula for the final amount with the compound interest formula can be given as,

$A=P\left(1+\dfrac{R}{n\times100}\right)^{nt}$

Here, A is the final amount (principal plus interest amount) on the principal amount P of with the rate r of in the time period of t.

Viola took out a $8,470 Stafford loan at the beginning of her four-year college career. The loan has a duration of ten years and an interest rate of 7. 5%, compounded monthly.

Put this values in the above formula as,

$A=8470\left(1+\dfrac{7.5}{12\times100}\right)^{12\times4}\\A=11422.6348$
