Solution
Q29. Profit-maximizing level of output or quantity is that quantity or output corresponding to which marginal revenue curve and marginal cost curve intersects each other.
As per given figure, marginal cost (MC) curve and marginal revenue (MR) curve are intersecting each other corresponding to output of 100 units.
So, profit-maximizing quantity for this firm is 100 units.
Q30. The price corresponding to profit-maximizng output with reference to demand curve is the profit-maximizing price.
With reference to demand curve, price corresponding to 100 units (profit-maximizing quantity) is $12 per unit.
So, profit-maximizing price is $12 per unit.
Q31. Quantity (as per Q29) = 100 units
Price (as per Q30) = $12 per unit
Average cost corresponding to 100 units is $4 per unit.
Calculate Total revenue -
Total Revenue = Price * Quantity = $12 * 100 = $1,200
Calculate Total cost -
Total cost = Average cost * Quantity = $4 * 100 = $400
Calculate Profit -
Profit = Total revenue - Total cost = $1,200 - $400 = $800
Thus, the firm will make a profit of $800.
