1. Depreciation Expense. The Sprague Company purchased a fabricating machine on April 1, 2018 at a net cost of $160,000. At the end of its 5-year useful life the company expects it will be worth $10,000. Sprague also estimates that the machine will run for 30,000 hours over its 5-year life. Compute depreciation for 2018 and 2019 using each of the following methods:

a. Straight-line

b. Sum-of-the-years digits

c. Double declining balance

d. Units of Production (the machine operated for 5,000 hours in 2018 and 6,000 hours in 2019)
