Answer:
Explanation:
amount of mortgage = $75,000
monthly installment for the 30 years = $498.97.
difference = total payment - the amount of mortgage = ( 30 × 12 ×$498.97) -  $75,000  = $ 104629.2
for the second,
( 15 × 12 × $674.12) - $ 75 000 = $ 46341.6
the difference in the total interest paid between the two different maturities = $ 104629.2 Â - $ 46341.6 Â = $ 58287.6
