Answer:
$240
Explanation:
To calculate the interest, you need to multiply the principal (the amount financed, $4,000.00) by the interest rate (2%) and the number of years (3).
So, the interest would be: $4,000.00 x 0.02 x 3 = $240.00
The contractor would pay $240.00 in interest over the course of the 3-year financing.
