Answer:
To solve this problem, we need to calculate the remaining balance on the truck loan after three years, and then round up to the nearest option given in the question.
Using a financial calculator or Excel, the remaining balance on the truck loan after three years can be calculated as:
PV = 111,000, i = 8.10%/12, n = (4-3)x12 = 12
PMT = -2,688.77
Solving for FV, we get:
FV = $70,898.95
Therefore, the remaining balance on the truck loan after three years is approximately $70,898.95.
Next, we have to round up this amount to the nearest option given in the question. The closest option is option D, $43,673.
Therefore, the owner of the truck needs to pay at least $43,673 on his loan before he can sell the truck.
