Final answer:
The interest rate associated with the loan is approximately 11.4%.
Step-by-step explanation:
To find the interest rate associated with the loan, we can use the formula for calculating the present value of an annuity. The present value of an annuity formula is:
Loan Amount = Payment Amount * (1 - (1 + Interest Rate)^(-Number of Payments))) / Interest Rate
Plugging in the given values, we have:
$9,725 = $2,500 * (1 - (1 + Interest Rate)^(-5))) / Interest Rate
Simplifying the equation and solving for the Interest Rate, we find that the interest rate associated with the loan is approximately 11.4%.
