Answer:
Depletion expense for the year is $280,000
Step-by-step explanation:
Depletion per unit = $3,500,000/ 500,000 = 7 per unit
Units produced during the year = 40,000
Cost depletion for the year = 40,000 * 7 = 280,000
Percentage depletion = (800,000 - 500,000) * 22% = 66,000
Since cost depletion is greater than percentage depletion, cost depletion is deducted.
Depletion expense for the year is $280,000
