Answer:
$545.74
Step-by-step explanation:
The actual mortgage is the purchase price minus the down payment, based on the mortgage amount, the monthly payment can be determined using a financial calculator as shown below:
N=360(number of monthly payments in 30 years=30*12=360)
I/Y=7.25/12(monthly interest rate without the "%" sign)
PV=-80000($100,000-20%*$100,000=$80000)
FV=0(after all required payments , the balance of the mortgage balance would be zero)
CPT
PMT=$545.74
