Final answer:
To find Terry's monthly vehicle payment, the cash-back incentive is subtracted from the MSRP to find the loan amount, then a loan payment formula or calculator is used with the loan amount, annual interest rate divided by 12 for monthly rate, and a 6-year term to find the monthly payment.
Step-by-step explanation:
To determine Terry's approximate monthly payment for the vehicle, we can use the formula for calculating loan payments. Firstly, let's subtract the cash-back incentive of $1,700 from the vehicle's MSRP which is $15,999 to get the initial loan amount. So, $15,999 - $1,700 = $14,299.
Now, we need to calculate the monthly payment using the loan amount, interest rate, and loan duration. The formula for the monthly payment (M) of a fixed-rate loan is M = P [ r(1 + r)^n ] / [ (1 + r)^n – 1], where:
- P is the principal amount (loan amount), which is $14,299.
- r is the monthly interest rate, which is (4% per year / 12 months) = 0.003333.
- n is the total number of payments (loan term in months), which is 6 years * 12 months/year = 72 months.
Using these values, we can calculate Terry's approximate monthly payment. However, since we can't include full mathematical calculations here, we'd typically input these values into a loan calculator to determine the exact monthly payment.
