John is a college student who works part-time at a campus restaurant. He is paid $8/hour and has no non-labor income. Assume there are 168 possible hours in a week that can be devoted to leisure or work.

1. Graph Johns budget constraint and label the utility-maximizing outcome if John opts to work 40 hours per week.
2. Suppose Johns parents decide to send him $100/week. Graph Johns new budget constraint.
3. How many hours will John now have to work to maintain the same weekly income as in (1)?
