Given:
Addy takes out a $14,000 personal loan to make home repairs.
Her interest rate is 7.6% on a 4-year loan.
Her monthly payments are $339.16
The total months = 4 * 12 = 48 months
The total payback amount = 48 * 339.16 = $16,279.68
The amount of the interest = 16,279.68 - 14,000 = 2,279.68
So, the answer will be:
Total payback = $16,279.68
The interest = $2,279.68
