Your firm's research department has estimated your total benefits to be TB=300Q-6Q^2 and your Total Cost =4Q^2. What level of Q will yield the maximum benefit?
Firm will get maximum benefit/profit at that level of output when marginal benefit from producing that level of outpit is equal to marginal cost incurred at that level of output.
Total benefit (TB)= 300Q- 6Q^2
Marginal benfit = dTB/dQ = 300-12Q
Total cost (TC)=4Q^2
Marginal cost = dTC/dQ = 8 Q
Maximum benefit will be attained when Marginal benefit = Marginal cost
300-12Q= 8Q
20Q=300
Q=15
Output level (Q)= 15 will yield the maximum benefit to the firm.
