Assume that a competitive firm has the total cost function:
TC=1q3−40q2+710q+1700TC=
Suppose the price of the firm's output (sold in integer units) is $550 per unit.
By creating tables (but not using calculus) with columns representing cost, revenue, and profit to find a solution, what is the total profit at the optimal output level?

30 | 14000 | 16500 | 2500 |
Cost: TC=1q3−40q2+710q+1700
Revenue: TR = output * price
Note: Price = $550 per unit
We can see that profit is maximum at output level of 24 units.
The total profit at the optimal output level is 3676
