Final answer:
To find the interest and total due on a loan, use the formula Interest = Principal Amount * Interest Rate * Time, and Total Due = Principal Amount + Interest. For Lex's loan of $2500 with an interest rate of 3.5% for 9 months, the interest is $65.63 and the total due is $2565.63.
Step-by-step explanation:
To find the interest and the total due on a loan, we can use the formula:
Interest = Principal Amount * Interest Rate * Time
Total Due = Principal Amount + Interest
Using this formula, we can calculate the interest and total due for Lex's loan:
Interest = $2500 * 0.035 * 9/12 = $65.63
Total Due = $2500 + $65.63 = $2565.63
Therefore, the correct answer is a) Interest: $65.63, Total Due: $2565.63
