Final answer:
The amount of interest you would pay is $2,531.25.
Step-by-step explanation:
To calculate the amount of interest you would pay, you need to first calculate the interest for the 27 months. The formula for simple interest is: interest = principal * rate * time.
In this case, the principal is $15,000, the rate is 8.5%, and the time is 27/12 = 2.25 years. Plugging these values into the formula:
interest = $15,000 * 0.085 * 2.25 = $2,531.25
So, you would pay $2,531.25 in interest.
