Assume that fruit-picking can be done by children or adults, but that adults are twice as efficient as children ( they pick twice as fast). The production function for fruit-picking is thus

Q = 10 x (2L_A + L_C)

Where output is measured in bushels of apples, labor is measured in days, L_A is the number of days of adult labor, and L_C is the number of days of child labor.

A) Depict the isoquants for a typical orchard (in terms of fruit-picking)

B) Assume the wage rate of adults is $100 per day, and the wage for children is $60 per day. Show the isocost lines
