Answer: $787.50
Explanation:
Firms maximise their profit levels at the point where Marginal Revenue equals Marginal Cost because at this point any increase in Cost will not bring about more additional revenue.
The point where MR = MC is point A where sales are 225 units and price is $3.50.
The Total Revenue = Price * Quantity
= 225 * 3.50
= $787.50
