Below are sample questions representative of the exercises included on this worksheet and related 7.45 Scarcity, Choice, and Opportunity Cost skill assessments:

Problem 1Difficulty: Mastery
An individual has 6 hours. They can either (A) cook at home for 2 hours and save $25 compared with eating out, or (B) work overtime for $20/hour. They choose to cook at home and do not work overtime.
What is the opportunity cost of cooking at home (in dollars), using the overtime wage as the value of time?
A$25
B$15
C$120
D$40
Solution & Explanation:Cooking takes 2 hours. If those 2 hours could have been used to earn $20/hour overtime, foregone wages are 2×$20=$40. That is the opportunity cost of cooking instead of working.
Problem 2Difficulty: Mastery
A town is deciding whether to convert a rail line into a trail. Current rail use saves commuters 5 minutes each day for 2,000 commuters. The trail is expected to generate $150,000 per year in tourism.
Which is a key opportunity cost of converting the rail line to a trail?
AThe tourism money that would be gained
BThe cost of painting trail signs
CThe value of commuter time savings that would be lost
DThere is no opportunity cost because the rail line already exists
Solution & Explanation:Converting to a trail gives up the rail service. The lost commuter time savings is a real opportunity cost even if it is not a direct cash payment.
Problem 3Difficulty: Mastery
A company has 100 engineer-hours. Project Alpha: each 10 hours adds $8,000 expected profit. Project Beta: each 10 hours adds $6,500 expected profit. Project Gamma: each 10 hours adds $7,500 expected profit. The company can fund only one project this month.
If the company funds Project Beta, what is the opportunity cost in expected profit?
A$7,500 per 10 hours (Gamma’s gain)
B$8,000 per 10 hours (Alpha’s gain)
C$6,500 per 10 hours (Beta’s gain)
D$22,000 per 10 hours (sum of all)
Solution & Explanation:The best alternative is Alpha at $8,000 per 10 hours. Funding Beta gives up Alpha’s higher expected profit.
