On the same graph, draw the indifference curves for two different people one (Mindy) who hates night work and one who only slightly dislikes nightwork (David). Have the x-axis be the share of night shifts 0 to 100%

b) Name a firm/industry where it is relatively cheap to eliminate night work and a similar firm/industry where it would be expensive to eliminate night work. Assume both firms would earn zero profits if the worker were to work nights 40% of the time and earned a wage of $15. Show the isoprofit curves that correspond to zero profits for these firms/industries.

c) According to your graph, which firm will David work for? Given the numbers on your graph, guestimate his wage rate and the share of night shifts.
