Answer:
C. The company will be $33,000 better off over the 5-year period if it replaces the old equipment.
Step-by-step explanation:
keep old machine:
operating expenses = $46,000 x 5 = $230,000
new machine:
purchase cost $260,000 - $28,000 = $232,000
operating expenses = $19,000 x 5 = $95,000
increase in revenue $26,000 x 5 = $130,000
if new machine is purchased, operating costs decrease by $135,000, revenues increase by $130,000, but investment outflows increase by $232,000 ⇒ $135,000 + $130,000 - $232,000 = $33,000
