Question

Carrie borrowed $800 dollars from her aunt at 8% interest per year. If she paid her a total of $448 in simple interest, how many years did it take her to pay her aunt back?

Answer 1

13 years

Explanation:

First we will have to see how much she owns her aunt:

800-448= 362

8% of 348 = 27.84

362 ÷ 27.84 = 13 years

I might be wrong but hopefully this helps :)
