Answer:
depletion of the timber tract = $228,000 and
depreciation of the logging roads = $22,800
Explanation:
Timber tract
Depletion rate = (Cost - Residual Value) ÷ Estimated units
= ($2,950,000 - $670,000) ÷ 5,700,000
= $0.40
Depletion expense = Units used x Depletion rate
= 570,000 x $0.40
= $228,000
Logging Roads
Depreciation rate = (Cost - Residual Value) ÷ Estimated units
= ($228,000 - $0) ÷ 5,700,000
= $0.04
Depreciation expense = Units used x Depreciation rate
= 570,000 x $0.04
= $22,800
