A firm operates in aperfectly competitive market . The market price of it's product is 4 birr and the total cost function is given by TC=1/3Q^3-5Q^2+20Q+50,Where TC is the total cost and Q is the level of output
A. What level of output should the firm produce to maximize it's profit ?
B. Determine the level of profit at equilibrium ?
C. What minimum price is required by the firm to stay in the market ?
"TC=\\frac 13Q^3-5Q^2+20Q+50,"
"TC'=Q^2-10Q+20,"
"TC''=2Q-10,"
"TC''=0,"
"Q=5,"
"TC'=-5."
