Final answer:
Jessica will pay $6,000 in interest if she pays off the loan at the end of the third year. The total amount that she will repay is $31,000.
Step-by-step explanation:
To calculate the interest that Jessica will pay if she pays off the loan at the end of the third year, we can use the formula:
Interest = Principal * Rate * Time
Interest = $25,000 * 8% * 3 years = $6,000
Therefore, Jessica will pay $6,000 in interest if she pays off the loan at the end of the third year.
To calculate the total amount that Jessica will repay, we need to add the principal and the interest:
Total amount = Principal + Interest
Total amount = $25,000 + $6,000 = $31,000
Therefore, Jessica will repay a total amount of $31,000.
