Please help with this question If a competitive firm finds that its average variable cost is decreasing at its current profit maximizing quantity, should the firm increase or decrease output?
Suppose that each firm in a competitive industry has the following costs:
Total cost: TC = 50 + 1/2q2
Marginal cost: MC = q
Where q is an individual firm’s quantity produced. The market demand curve for the product is:
Demand: QD = 120 – P
Where P is the price and Q is the total quantity of the good. Currently there are 9 firms in the market.
What is each firm’s fixed cost? What is its variable cost? Give the equation for average total cost.
Graph the average-total-cost curve and the marginal-cost curve for q from 5 to 15. At what quantity is the average-total-cost curve at its minimum? What is the marginal cost and average total cost at that quantity?
Give the equation for each firm’s supply curve.
Give the equation for the market supply curve for the short run in which the number of firms is fixed.
What is the equilibrium price and quantity for the market in the short run?
In this equilibrium, how much does each firm produce? Calculate the firm’s profit and loss. Do firms have…

If they were to price their product higher, they will sell zero. Which of the following is true?
