Step 1 :Fritz's monthly payment is \( \$344.42 \).
Step 2 :He makes payments for 4 years, which is \( 48 \) months.
Step 3 :So, the total amount he will pay over the 4 years is \( \$344.42 \times 48 = \$16532.16 \).
Step 4 :The original cost of the car is \( \$14000 \).
Step 5 :To find the total amount of interest Fritz will pay, we subtract the original cost of the car from the total payment. So, the total interest is \( \$16532.16 - \$14000 = \$2532.16 \).
Step 6 :Final Answer: Fritz will pay a total of \(\boxed{2532.16}\) in interest.
