Final answer:
The APR of Eric's car loan is 7.2%.
Step-by-step explanation:
To calculate the Annual Percentage Rate (APR) of Eric's car loan, we need to first convert the monthly interest rate to an annual rate. Since there are 12 months in a year, the annual interest rate will be 12 times the monthly interest rate. So, the annual interest rate is 0.6% x 12 = 7.2%.
The APR of Eric's car loan is 7.2%.
