Your brother lends you $125 at an annual interest rate of 25%. If you want to pay no more than $62.50 in simple interest, in how many years will you need to pay off the loan?

Use the formula: [tex]I = Prt[/tex].

Answer :

Final answer:

To pay off the loan within $62.50 in simple interest, you will need 2 years.

Explanation:

To calculate the time it will take to pay off the loan, we can use the formula I = Prt, where I is the interest, P is the principal amount (loan amount), r is the interest rate, and t is the time (in years).

In this case, the interest is $62.50, the principal amount is $125, and the interest rate is 25% (or 0.25).

So we have the equation 62.50 = 125 × 0.25 × t. Dividing both sides of the equation by 31.25, we get t = 2 years.

Therefore, you will need to pay off the loan in 2 years.
