Suppose the supply function for product X is given by

Suppose the supply function for product X is given by QXS = - 30 + 2Px - 4Pz. a. How much of product X is produced when Px = $600 and Pz = $60? b. How much of product X is produced when Px = $80 and Pz = $60? c. Suppose Pz = $60. Determine the supply function and inverse supply function for good X. Graph the inverse supply function. Supply function: QXS =

Inverse supply function: PX = Graph the inverse supply function from QX = 0 to QX = 200
