Demand function - Qd = 200-5(own price)+2(Alpha price)+2(Beta price).
Cost Function = 200-20Q
MC = $20
What is the inverse demand function?
Solve for MR = MC as well.
Demand Function: Qd= 200-5(own price)+2(Alpha price)+2(Beta price).
Own Price= (200/5)+(2/5)(Alpha Price)+(2/5)(Beta Price)- (1/5)Qd
Own Price= 40+0.4(Alpha Price)+0.4(Beta Price)-0.2Qd
Inverse demand function: Own Price= 40+0.4(Alpha Price)+0.4(Beta Price)-0.2Qd
Total Revenue= 40Qd+0.4(Alpha Price)Qd+0.4(Beta Price)Qd- 0.2Qd2
Marginal Revenue= 40+0.4(Alpha Price)+ 0.4(Beta Price)- 0.4Qd
Marginal Revenue= Marginal Cost
40+0.4(Alpha Price)+ 0.4(Beta Price)- 0.4Qd= 20
40+0.4(Alpha Price)+ 0.4(Beta Price)-20= 0.4 Qd
Qd= 100+(Alpha Price)+(Beta Pridet)- 50
Qd= 50+(Alpha Price)+(Beta Price)
