First, obtain the M R curve of the rm:
T R(Q) = P (Q) Q = (20 0.2Q) Q = 20Q 0.2Q2 ,
dT R
= 20 0.4Q.

M R(Q) =
To maximise prots, the rm sets M R = M C.
M R(Q) = 20 0.4Q = M C(Q)

1. 1) N=sqrt(S/bF)=sqrt(375)=19.36
Hence, if N=20, profits are negative, and if N=19, profits are positive.
Equilibrium N has to be an integer and hence N=19, since no more firms will
want to enter (N=20 leads to negativ
