Answer:
C. $3,500
Explanation:
The formula for a straight-line method of depreciation is provided below:
annual depreciation charge=(cost-salvage value)/useful life
cost of the new truck=$42,000
salvage value=$0
useful life=7 years
depreciation=($42,000-$0)/7=$6,000( same as given in the question)
The truck was used for 7 months in the first year ended, from June 1 2019 to December 31 2019
Depreciation for the first year=$6000*7/12=$3,500
