To calculate the difference in monthly payments between financing the new car and financing the used car, we will use the formula for the monthly payment of a loan:

$PMT = \frac{P \left( \frac{r}{n} \right)}{1 - \left(1 + \frac{r}{n}\right)^{-nt}}$

Where:

• $P$ is the loan amount,
• $r$ is the annual interest rate (as a decimal),
• $n$ is the number of payments per year (12 for monthly payments),
• $t$ is the loan term in years.

For the new car:

• Loan amount $P$ = $26,000
• Annual interest rate $r$ = 5.29% = 0.0529
• Loan term $t$ = 5 years
• $n$ = 12 (monthly payments)

For the used car:

• Loan amount $P$ = $16,000
• Annual interest rate $r$ = 6.45% = 0.0645
• Loan term $t$ = 5 years
• $n$ = 12 (monthly payments)

Let's calculate the monthly payments for both cars and then find the difference.# Defining the loan parameters def calculate_monthly_payment(P, r, n, t): # Calculate the monthly interest rate monthly_interest_rate = r / n # Calculate the total number of payments total_payments = n * t # Using the PMT formula payment = (P * monthly_interest_rate) / (1 - (1 + monthly_interest_rate) ** -total_payments) return payment

New car loan parameters

P_new_car = 26000 # Loan amount for the new car r_new_car = 0.0529 # Annual interest rate for the new car n = 12 # Number of payments per year t = 5 # Loan term in years

Used car loan parameters

P_used_car = 16000 # Loan amount for the used car r_used_car = 0.0645 # Annual interest rate for the used car

Calculate monthly payments for both new and used car

monthly_payment_new_car = calculate_monthly_payment(P_new_car, r_new_car, n, t) monthly_payment_used_car = calculate_monthly_payment(P_used_car, r_used_car, n, t)

Calculate the difference in monthly payments

monthly_payment_difference = monthly_payment_new_car - monthly_payment_used_car monthly_payment_new_car, monthly_payment_used_car, monthly_payment_differenceThe monthly payment for the new car would be approximately $494.11, while the monthly payment for the used car would be approximately $312.68.

The difference in monthly payments between financing the new car and the used car is about $181.43.
