1. Why do garbage collectors make more than furniture movers?
2. What are union wages? Why are some employers willing to pay them?
3. Maria is a hostess at a local restaurant. When she earned $8 per hour, she worked 35 hours per week. When her wage increased to $10 per hour, she decided to work 40 hours. However, when her wage increased again to $12 per hour, she decided to cut back to 37 hours per week. Draw Maria's supply curve. How would you explain her actions to someone who is unfamiliar with economics?
