Answer:
a. $390,000
b. $15.6
c. $28,860
Explanation:
depreciable cost = cost of asset - salvage value = $420,000 - $30,000 = $390,000
(b) The depreciation rate $ per hour = depreciable cost / estimated useful life = $390,000 / 25,000 = $15.6
The units-of-output depreciation for the year = $15.6 x 1,850 hours = $28,860
