Perdue company purchased equipment on april 1, 2014, for $270,000. the equipment was expected to have a useful life of three years, or 18,000 operating hours, and a residual value of $9,000. the equipment was used for 7,500 hours during 2014, 5,500 hours in 2015, 4,000 hours in 2016, and 1,000 hours in 2017.required: determine the amount of depreciation expense for the years ended december 31, 2014, 2015, 2016, and 2017, by (a) the straight-line method, (b) units-of-output method, and (c) the double-declining-balance method. note: for declining balance only, round the answer for each year to the nearest whole dollar. a. straight-line methodyear amount2014 $65,2502015 $87,0002016 $87,0002017 $21,750

Explanation:

Straight line:

(cost - salvage value) / useful life

(270,000 - 9,000)/3 = 87,000 per complete year

First year: from April 1st to December 31th

87,000 x 9/12 = 65,250

Second and third year are complete year thus, 87,000

fourth year: from Jan 1st to March 31th:

87,000 x 3/12 = 21,750

units-of-output method:

(cost - salvage value) / unit of output

261,000 / 18,000 = 14.5 per hour

We multiply each year hours by this rate

7,500 x 14.5 = 108,750

5,500x 14.5 =   79,750

4,000x 14.5 =   58,000

1,000 x 14.5 =   14,500

double declining

we multiply by twice the rate of of straight line:

1/3 x 2 = 2/3 we depreciate this amount of the carrying vbalue per year

Last year we adjust to obtain the residual value
