Answer: $30,000
Explanation:
Given the following :
Cost of machine = $375,000
Salvage value = $75,000
Useful years = 5years
Estimated runtime during useful years = 40000 hours
Actual runtime in 2021 = 4000 hours
Using the units-of-activity method of depreciation, the amount of depreciation expense for 2021 would be :
[(Cost of machine - salvage value) ÷ estimated runtime] × Actual runtime in 2021
[($375,000 - $75,000) ÷ 40000] × 4000
[ $300,000 ÷ 40,000] × 4000
$7.5 × 4000 = $30,000
