Explanation: Given client's annual demand curves: Client 1: Q1= 21- P Client 2: Q2= 18-2P P= 1/ 2*( 9- P)* Q2 Calculate total revenue of both the clients: TR1= r+ (P* Q1) = 1/ 2* (9- P)* Q2+ P*( 21- P) TR2= r+ (P* Q2) = 1/2* (9- P)* Q2+ P* (18- 2P) Calculate the total profit: Profit= TR1+ TR2- MC* (Q1+ Q2) = ((1/ 2* (9- P)* Q2+ P*( 21- PD)+ (1/2* (9- P)- Q2+ P* (18- 2P)))- (2 2* ((21- P)+ (18-2PM) = = (0/ 2* (9- P)* Q2+ P*( 21- PD)+ (1/2* (9- P) Q2+ P* (18- 2P)))- (2.2* (39-3P)) = 2* (1/ 2)* (9- P) Q2+ P* (21- P)+ P* (18- 2P)- (2 2* (39-3P)) = (9- P)* (18- 2P)+ 21P- P 2+ 18P- 2P 2- 85.8+ 6.6P = 2* (9- P)* (9- P)+ 45.6P- 3P 2- 85.8 = 2* (9- P)* 2+ 45.68- 3P 2- 85.8 Total profit is 2* (9- P)* 2+ 45.6P- 3P*2- 85.8 Differentiate with respect to P: ap = 2* 2* (9- P)- 1+ 45.6- 6P=0 -36+ 4P+ 45.6- 6P= 0 9.6-2P= 0 2P= 9.6 P= 9.6/ 2 = 4.8
