Joseph is a coach. He uses his own car to travel to various locations to meet clients. He acquired a car on 1 March 2020 for $30,000. The acquisition cost was funded entirely by a loan at an interest rate of 6%. He has determined that the depreciation deduction on the car would be $6,000 for the year. In addition, Joseph incurred the following expenses during the year:

Registration and insurance = $3,000;

Repairs and maintenance = $800; and

Oil and fuel costs = $1,500.

For the period 1 March 2020 to 30 June 2020, Joseph estimates that the car travelled a total of 8,000 kilometres; 6,000 of which were for business purposes. You may assume that Joseph has maintained all necessary records and a logbook. Assume that depreciation has been adjusted for partial year use and the impact of the car limit.
