Output Functions:

Qd=(195-2P)/4

Qc=1(95-1.5P)/4

Profit function:

d(P)=(195-2P/8)^2+140P

c(P)=(195-1.5P/8)^2+140P-300

Identify the optimal contingent permit price plan using various price levels for P.

Then using the data graph two profit functions and illustrate the breakeven price.

Find the breakeven price P by solving your profit indifference equation.
