Answer:
$550.97
Step-by-step explanation:
The amortization formula will tell you the payment amount.
A = P(r/12)/(1 -(1 +r/12)^(-12t))
where A is the monthly payment, P is the principal amount of the loan, r is the annual interest rate, t is the number of years. Using your values, this is ...
A = $12,000(0.095/12)/(1 -(1 +0.095/12)^(-12·2)) ≈ $550.97
The amount of Gerald's payment is $550.97.
