Depreciation Methods

Gruman Company purchased a machine for $198,000 on January 2, 2016. It made the following estimates:

Service life	5 years or 10,000 hours
Production	180,000 units
Residual value	$ 18,000

In 2016, Gruman uses the machine for 2,000 hours and produces 45,000 units. In 2017, Gruman uses the machine for 1,400 hours and produces 34,000 units. If required, round your final answers to the nearest dollar.

Required:

2. Sum-of-the-years'-digits method

   2016	$ fill in the blank 3
   2017	$ fill in the blank 4

3. Double-declining-balance method

   2016	$ fill in the blank 5
   2017	$ fill in the blank 6

4. Activity method based on hours worked

   2016	$ fill in the blank 7
   2017	$ fill in the blank 8

5. Activity method based on units of output

   2016	$ fill in the blank 9
   2017	$ fill in the blank 10

2. For each method, what is the book value of the machine at the end of 2016? At the end of 2017?
