Question 3 The supply Qs = s(P, Pm) has the functional form of: Qs = -12 + 0.5P - 2Pm initially, the materials cost Pm_0 = 6. In your worksheet, find the optimal quantity to supply if the price is P=76 and if P=80. At P=76, Q_0 = At P=80, Q_0 = In your worksheet, draw the supply curve, indicate the quantities supplied, and label everything you think relevant. Question 4 Now the cost of materials changes to Pm_1 = 8. In your worksheet, find the optimal quantity to supply if the price is P=76 and if P=80. At P=76, Q_1 = At P=80, Q_1 = In your worksheet, draw the second supply curve and show how supply shifted
