Answer:
a. $72,000
b. $0.36
c. $6,480
Explanation:
a. Depreciation cost = Cost of truck - Residual value
= $80,000 - $8,000
= $72,000
b. The depreciation rate = (Cost of truck - Residual value) ÷ Estimated total production
= ($80,000 - $8,000) ÷ 200,000 miles
= $72,000 ÷ 200,000 miles
= $0.36
c. The units-of-activity depreciation for the year per mile = Driven miles × Depreciation rate
= 18,000 × $0.36
= $6,480
