Answer:
1. This firm have the profit maximizing output level of 1400 units because a firm in any industry will maximize profit where MR=MC. Here MR is equal to MC at the output level of 1400. So profit maximizing level of output is 1400 units.
2. Economic profit = Total revenue - total cost.
Where, Total revenue = Quantity * price
= 1400 * 7
= $9,800
Total variable cost = AVC * quantity
= 6.50 *1400
= $9,100
Total fixed cost = AFC * quantity
= 0.80 * 1400
= $1,120
Economic profit = Total revenue - Total variable cost - Total fixed cost
Economic profit = $9,800 - $9,100 - $1,120
Economic profit = -$420
. The firm is having economic loss equal to 420.
Conclusion: This firm is facing economic loss in its output.
