Final answer:
The total amount to be paid at the end of the loan is $2,547.95.
Step-by-step explanation:
To calculate the total amount to be paid at the end of the loan, we need to calculate the interest accrued first.
Simple interest can be calculated using the formula I = P * r * t, where I is the interest, P is the principal (loan amount), r is the interest rate, and t is the time in years.
In this case, the interest can be calculated as follows:
I = 2500 * 0.07 * (90/365) = $47.95.
The total amount to be paid at the end of the loan is the sum of the principal and the interest:
Total amount = Principal + Interest = 2500 + 47.95 = $2,547.95.
