Lina purchased a new car for use in her business during 2015. The auto was the only business asset she purchased during the year and her business was extremely profitable. Calculate her maximum depreciation deductions (including 179 expense unless stated otherwise) for the automobile in 2015 and 2016 (Lina doesnt want to take bonus depreciation for 2015 or 2016) in the following alternative scenarios (assuming half-year convention for all and that 2014 179 amounts are extended to 2015):

a. The vehicle cost $40,000, and business use is 100 percent.

b. The vehicle cost $40,000, and she used it 80 percent for business

c. The vehicle cost $40,000, and she used it 80 percent for business. She sold it on March 1 of year 2.

d. The vehicle cost $40,000, and she used it 20 percent for business
