Answer: D. $90,518.40
Explanation:
They are putting a 20% down payment on the home which means they are paying 80%;
= 80% * 157,500
= $126,000
First find the monthly payments;
Present value = Payment * ((1 - (1 + r)^-n) / r)
n= 20 * 12 = 240 months
r = 6/12 = 0.5%
126,000 = Payment * (( 1 - ( 1 + 0.5%)⁻²⁴⁰) / 0.5%)
126,000 = Payment * 139.58077168292915831291691663652
Payment = 126,000/139.58077168292915831291691663652
Payment = $902.70313
They'll pay that for 240 months;
= 902.70313 * 240
= $216,648.7512
Interest = 216,648.7512 - 126,000
= $90,648.7512
= $90,648.75
