**Educational Website Content:****Scenario:**A firm sells its product in a perfectly competitive market where other firms charge a price of $90 per unit. The firm’s total costs are given by the equation C(Q) = 50 + 10Q + 2Q².**Instructions:** Round up your answers to no decimals.**Questions:**a. **How much output should the firm produce in the short run?** Q = [Answer to be calculated]b. **What price should the firm charge in the short run?** P = $[Answer to be calculated]c. **What are the firm’s short-run profits?** Profits = $[Answer to be calculated]d. **What adjustments should be anticipated in the long run?** [Choose A, B, C, or D] - **A.** Exit will occur since accounting profits are always zero in the long run. - **B.** No firms will enter or exit at these levels of profits. - **C.** More firms will enter the industry, increasing the supply, until economic profits shrink to zero. - **D.** More firms will enter the industry since economic profits are positive.

We are given , TC = 50 + 10q + 2q2 Since the firm sells it's product in a perfectly competitive market where other firms charge a price of $90 , Price = $90 We know , Total Revenue = Price * Quantity Total Revenue = 90 q We know , Profit = Total Revenue - Total Cost Profit = 90q - 50 - 10q - 2q2 Profit = 80q - 2q2 - 50 TR = 90q MR = dMRdQ MR = 90 TC = 50 + 10q + 2q2 MC = dTCdQ MC = 10+ 4q We know that the profit is maximized at a point where , MR=MC 90 = 10 + 4q q = 20 (a.) The firm should produce 20 units in the short run. (b.) The firm should charge $90 per unit in the short run.(c.) Profit = 80q - 2q2 - 50 Now putting q = 20 Profit = 80(20) - 2(20)2 - 50 Profit = 1600 - 800 - 50 Profit = $750

Glowglobes are produced by identical firms in a perfectly competitivemarket. There are 22 firms in the market. Each firm's Total Cost functionis TC=473+2q+q^2 and Marginal Cost function is MC=2+2q. Marketdemand is Q=485-P. What is the quantity produced by each firm in the short-run?
If a perfectly competitive firm's average total cost is less than the price, then the firm A) incurs an economic loss. B) makes an economic profit. C) makes zero economic profit. D) makes either zero economic profit or an economic profit depending on whether the marginal revenue is equal to or greater than the price. E) None of these answers is correct because the relationship between the price and average total cost has nothing to do with the firm's profit.

Refer to the figure above. When the demand curve is given by P2 = $15, this firm should ______ A. continue to operate in the short run and think about shutting down in the long run B. discontinue operation in the short run since there is a loss when operating. C. keep operating as long as loss is not greater than total cost D. discontinue operation in the short run since average total cost is greater than price. When the demand is P3 = $10, this firm should ______ A. continue to operate in the short run and think about shutting down in the long run B. discontinue operation in the short run since the firm is unable to cover variable costs. C. keep operating as long as loss is not greater than total cost D. discontinue operation in the short run since average total cost is greater than price.
A competitive firm's total cost is TC(Q)=3Q2+2Q+47 when the output level is Q. Accordingly, its marginal cost is MC(Q)=2*3*Q+2. The market price is P=14. You are told that the firm will not shut down in the short run. Please find its profit at the optimal output level.
Consider a firm with a short run Total Cost (TC) given by TC=900+15Q-8Q2+2Q3. What is the firm's marginal cost? What is firm's shut down price?
A profit-maximizing firm decides to shut-down production in the short-run. Its total fixed cost of production is $100, i.e. TFC = $100. Which of the following statements is true? a If the firm produced, the firm's revenues would have been lower than $100. bIf the firm produced, the firm's total variable cost must be lower than $100. cIf the firm produced, the firm's losses would have been higher than $100. dIf the firm produced, the firm's total variable cost would have been higher than $100.
