Answer:
$50,000
Step-by-step explanation:
Estimated Cost of New Equipment = $500,000
Useful life in years = 5
Estimated Residual Value = $50,000
Expected New Cash Inflows over life of asset = $700,000
Annual depreciation expense = (Estimated Cost of New Equipment-Estimated Residual Value)/Useful life in years
= ($500,000 - $50,000) / 5
= $450,000 / 5
= $90,000
Average annual cash flow = Expected New Cash Inflows over life of asset/ Useful life in years
= $700,000/5
= $140,000
Average annual operating income = Average annual cash flow - Annual depreciation expense
= $140,000 - $90,000
= $50,000
