1. using the demand function (Qdx = 20 - 0.4Px), calculate the quantity demanded assuming the following prices: (a) show the solution (3 pts each) (b) make table and graph (2pts each) 1.) P = 40 2.) P = 50 3.) P = 60 2. using the supply function (Qsx = -10 + 0.6Px), calculate the quantity demanded assuming the following prices: (a) show the solution (3pts each) (b) make table and graph (2pts each) 1.) P = 35 2.) P = 45 3.) P = 55
