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 (2LA + Lc)
where output is measured in bushels of apples, labour measured in days, LA is the number of days of adult labour, and Lc is the number of days of child labour.
