Answer: $671.03
Explanation:
The monthly payment will be an annuity because it will be constant. The loan amount will be the present value of the loan.
Periodic interest rate of loan = 5%/12 = 5/12%
Loan period = 30 * 12 months = 360 months
Present value of annuity = Annuity * ( 1 - ( 1 + rate) ^ -number of periods) / rate
125,000 = Annuity * ( 1 - ( 1 + 5/12%)⁻³⁶⁰) / 5/12%
125,000 = Annuity * 186.2816170
Annuity = 125,000 / 186.2816170
= $671.03
