Use 41the following general linear supply function:

Qs = 40 + 6P 8PI + 10F

where Qs is the quantity supplied of the good, P is the price of the good, PI is the price of an input, and F is the number of firms producing the good. If PI = $20, F = 60, and the demand function is Qd = 600 6P the equilibrium price and quantity are, respectively,
