Perdue Company purchased equipment on April 1 for $93,420. The equipment was expected to have a useful life of three years, or 7,560 operating hours, and a residual value of $2,700. The equipment was used for 1,400 hours during Year 1, 2,600 hours in Year 2, 2,300 hours in Year 3, and 1,260 hours in Year 4.

The depreciation cost per year is:

Year 1: $16,800

Year 2: $31,200

Year 3: $27,600

Year 4: $15,120

Explanation:

To calculate the depreciation cost for the equipment based on hours used, we must determine the cost per hour:

cost per hour = (purchase cost - salvage value) / expected useful life

cost per hour = ($93,420 - $2,700) / 7,560 hours = $90,720 / 7,560 hours = $12 per hour

The depreciation cost per year is:

Year 1: 1,400 hours x $12 per hour = $16,800

Year 2: 2,600 hours x $12 per hour = $31,200

Year 3: 2,300 hours x $12 per hour = $27,600

Year 4: 1,260 hours x $12 per hour = $15,120
