A producer's supply function is given by the equation: Q(s) = -55+26P(S) +1.3P(a). Where Q(s) is thr quantity of steel supplied by the market, P(s) is the per unit price of steel and P(a) is the per unit price of aluminum.
a. If the unit price of aluminum is 10, what is the slope of the supply curve ?
b. Assume the s upply side of the market consists of exactly 5 indentical sellers.If the unit price of aluminum is 20, what is the equation for the market inverse supply function?
