A company wants to buy 20 tractor trailers. The cost of each tractor trailer is $150,000. These assets are expected to have a useful life of 7 years (1,000,000-mile life) and a salvage value of 20% of the original cost. It is estimated that in the first year, each truck would be driven 100,000 miles and 150,000 miles in year 2. Although the useful life is 7 years, the company is expected to trade-in these tractors for new ones at the end of 5 years. Prior to depreciation and taxes, the companys income is 1,500,000 and it is in the 21% corporate tax rate. The average assets of the company are $15,000,000 and the average equity is $1,000,000.
