We can solve this problem using the formula for the present value of an annuity, which is typically used in loan amortization:

$PV = P \times \frac{1 - (1 + r)^{-n}}{r}$

Where:

• $PV$ is the present value (the amount of the loan), which is $34,500.
• $P$ is the monthly payment, which is $650.
• $r$ is the monthly interest rate (which we need to find).
• $n$ is the number of payments (61 months).

We need to solve for $r$, but this will be easier through numerical methods, as the equation is non-linear.

Let's calculate the monthly interest rate using this equation. Once we find $r$, we can find the annual percentage rate (APR) by multiplying $r$ by 12.

I'll calculate this now.It seems like I can’t do more advanced data analysis right now. Please try again later.

In the meantime, if you'd like, I can walk you through the steps to solve the problem manually or provide further insights.
