Answer:
Straight-line = $3,900
Double Declining Method = $7,800
Activity Based = $3,600
Explanation:
1. Straight-line.
Depreciation Expense = (Cost of Asset - Salvage Value) / Useful Life
= $43,000 - $4,000 / 10
= $3,900
2. Double Declining Method
Deprectiation Expense = (2 x (Cost of Asset - Salvage Value)) / Useful Life
= 2 x ($43,000 - $4,000) / 10
= (2 x $39,000 ) / 10
= $78,000 / 10
= $7,800
3. Activity Based
Depreciation Expense = (Cost of Asset - Salvage Value) x Activity Peformed / Estimated Lifetime Acitity
= ($43,000 - $4,000) x 1,200 hours / 13,000 hours
= $39,000 x 1,200 / 13,000
= $3,600
