Janeanne borrowed $7,500 to buy a used car. the interest rate on the loan
was 5.5%. if janeanne repaid a total amount of $9,975, how many years
did janeanne borrow the money for?

Around 5 years

Unless I did my work incorrectly, Janeanne borrowed for a little longer than 5 years but a LOT less than 6 years. Overall, she was closer to 5 years than she was 6 years.

Step-by-step explanation:

Presumably, each year, her interest rate went up along with her new total loan amount (thanks to the interest).

Initially: She owed $7,500

1st year: Since her interest rate is 5.5%, we have to find 5.5% of the original loan amount ($7,500) which is $412.50. Now we add that 5.5% onto the original loan.

2nd year: Now that she owes $7912.50, we need to find 5.5% of THAT loan amount, which is $435.19. Now we add again.

3rd year: We're at three years now and Janeanne owes around $8347.69. We once again find 5.5% of THIS amount of money. 5.5% is $459.12

.

4th year: At the 4 year mark, Janeanne owes $8806.81. 5.5% of that is $484.37. The total sum of these is:

5th year: At 5 years, Janeanne owes $9291.18. 5.5% is 511.01. Let's add them together:

6th year: Now at 6 YEARS, Janeanne owes $9802.19. 5.5% of this loan amount is $539.12. Added together, they equal:

Janeanne borrowed the money for little over 5 years. :)
