If she works she must spend $300 a week on childcare regardless of how many hours she works. a) Draw her budget constraint.

(Please show the new equilibrium on your graph in part a) (1 pts) d) The government decides to make childcare free. If she was previously working 0 hours a week what will happen to her labor supply?
