A firm that operates in a competitive market has a total cost of production given by TC(Q) = 3,000 + 5 Q + 18 Q2 and marginal cost given by MC(Q) = 5 + 36 Q. The market price for the product it sells is P = $239. Then the profit maximizing quantity is
- Q = 234
- Q = 6.5
- Q = 7.8
- None of the above
