Step-by-step explanation:
Deshaun and Marsha are considering a $175,000 mortgage for 15 years at a 4.4% interest rate, with a monthly payment of $1329.81. To calculate the total payback of this loan, you would multiply the monthly payment by the number of months in the term: $1329.81 * (15 years * 12 months/year) = $238,964.60. To find out how much of this total payback is interest, you subtract the original loan amount from the total payback amount: $238,964.60 - $175,000 = $63,964.60. Therefore, the total amount paid in interest would be $63,964.60.
