To calculate Trevor's monthly payment, we can use the formula for the monthly payment of a loan:
P = (Pr) / (1 - (1+r)^(-n))
where P is the monthly payment, P is the principal (loan amount), r is the monthly interest rate, and n is the total number of payments (number of years multiplied by 12 months per year).
Here, P = $22,000, r = 0.0725 / 12 = 0.00604166667, and n = 5 * 12 = 60.
Plugging these values into the formula, we get:
P = (22000 * 0.00604166667) / (1 - (1 + 0.00604166667)^(-60))
P ≈ $430.55
Therefore, Trevor's monthly payment would be approximately $430.55. I only have the first one lol
