Answer:
Simple rate of return on the investment is 18%
Step-by-step explanation:
Initial investment = Cost of the new machine - Salvage value of old machine
=$426,000 - $24,000 = $402,000
Annual cost savings = $147,000
Annual depreciation = $426,000 / 6 = 71,000
Annual incremental net operating income = $147,000 - $71,000 = $76,000
Simple rate of return on the investment = $71,000 / $402,000
=0.18
=18%
