Assume that in a perfectly competitive environment there are five firms competing with each other's. The cost curves of each firm are given by the following equations:

C_i=i Q_i² i= 1, 2 , 3 , 4 ,5

5

and 1/_i =30 ₁ * ₂ * ₃ * _{4 * 5} =1/4

i=1

By assuming P = 100 - 0.20Q is the industry demand function find the equilibrium Price, Quantity and Profit of each firm.
