Answer:
$125,500
Step-by-step explanation:
The initial cost of coal mine=$1,004,000
Estimated useful life=56,000 tons of coal
tons of coal extracted in the first year=7,000 tons
depletion expense=(cost of coal mine-residual value)*tons of coal extracted in the first year/estimated useful life
residual value =$0
depletion expense=($1,004,000-$0)*7000/56000
depletion expense=$1,004,000*7000/56000
depletion expense for first year=$125,500
