Answer:
$124,440
Step-by-step explanation:
Given a monthly principal and interest payment of $679, over the 30 year period, Naomi would have paid back
$679 * 30 year * 12 months in a year
= $244,440
With a loan amount of @120,000, the interest portion of the total repayment is therefore = total repayment less the loan amount
= $244,440 - $120000
= $124,440.
