Answer:
$143.30
Step-by-step explanation:
In order to determine the principal reduction payment, the monthly interest will need to be calculated. The interest will then be deducted from the total monthly payment to compute the principal reduction payment:
Annual Interest = $118,000 X 7/100
= $8,260
Monthly interest = $8,260/12
= $688.33
Principal reduction = $831.63 - $688.33
= $143.30
