<br>1) An imperfectly competitive firm has the following demand and cost functions:

<br>P=230-20Q

<br>C=50+30Q

<br>

<br>a. What is optimum output?

<br>b. What is equilibrium price of this output per unit?

<br>c. What is optimal revenue?

<br>d. What is total profit?

<br>

<br>For optimum in an imperfectly competitive firm, MR = MC

<br>

<br>Total Revenue = TR = Price * Quantity = P*Q

<br> = (230-20Q)*Q = 230Q - 20Q^2

<br>MR = d(TR)/dQ = d(230Q - 20Q^2)/dQ = 230 - 40Q

<br>MC = dC/dQ = 30

<br>MR = MC ==> 230-40Q = 30 ==> ...
