Answer:
$10,000
Step-by-step explanation:
The opportunity cost of the idle machine when considering Alternative 2 can be calculated by deducting the benefit from alternative 2 from the benefits of alternative 3
DATA
Benefits from alternative 1 = $50,000
Benefit from alternative 2 = $60,000
Benefit from alternative 3 = $70,000
Net financial benefit from Alternative 3 = Benefit from alternative 3 - opportunity cost
Net financial benefit from Alternative 3 = $70000-60000
Net financial benefit from Alternative 3 = $10000
