Final answer:
To find the total amount Jack will pay to repay the loan in 3 months, calculate the interest for one year, then for 3 months, and add it to the principal.
Step-by-step explanation:
To calculate the total amount Jack will pay, we need to calculate the interest for the 3 months he takes to repay the loan. First, we need to calculate the interest for one year using the formula: Interest = Principal * Rate. In this case, Principal = $2,700 and Rate = 8.2%. So, Interest = $2,700 * 0.082. Next, we need to calculate the interest for 3 months. Since 1 year = 12 months, 3 months is 1/4 of a year. So, Interest for 3 months = (Interest for 1 year) * (1/4). Finally, we add the interest for 3 months to the principal to get the total amount Jack will pay.
