Answer:
a) $648,000
b) $1,127,520
c) $479,520
Step-by-step explanation:
First, we need to find how much is 20% if $810,000.00, so
$810,000 x 20% = 810,000 x 20 / 100 = $162,000
It means that Donna makes a down payment of $162,000. So, the amount that she borrow was:
$810,000 - $162,000 = $648,000
So, the principal of her mortgage was $648,000
On the other hand, she will pay $6,264 every month for 15 years, so she will pay a total of
$6,264 x 12 x 15 = $1,127,520
So, she will pay a total of $1,127,520 on the loan.
Finally, the interest will be the difference between the principal and the total pay
$1,127,520 - $648,000 = $479520
Therefore, the answers are:
a) $648,000
b) $1,127,520
c) $479,520
