(b) For all hours Tom works up to his first 40, what is his after-tax, after-child care wage? If he works 40 hours, what is his consumption level and hours of leisure?

(c) For all hours Tom works over 40, what is his after-tax and after-child care wage? If he works for 110 hours and has no leisure at all, what is his consumption level?
