The acquisition cost was funded entirely by a loan at an interest rate of 15%. He has determined that the depreciation deduction on the car would be $2,300 for the year. In addition, Kumpole incurred the following expenses during the year:

1. Oil and fuel costs = $1,500;
2. Repairs and maintenance = $1,000; and
