Accounting and Economic Profit analysis

One comes across the concept of Profits in the context of business and in analyzing the results of business activity. Profits of a business can be accounting profits, and they can also be economic profits. So how does one understand the concept of accounting versus economic profits?

Question

In the short-run, if a perfectly competitive firm chooses to produce, then its profits are maximized by producing the quantity of output where price (P) = marginal cost (MC).

A perfectly competitive firm sells its good for $20. If marginal cost is four times the quantity produced, how much does the firm produce? Why? Assuming perfect competition, there is not enough information to determine how much the firm is producing. Assuming perfect competition, the firm is producing where MC is twice MR. If the price is $20, then MC is $40. This means that the firm is producing 10 units. Assuming perfect competition, the firm is producing where MR = MC. If the price is $20 and MC is four times the quantity, it is producing 80 units. Assuming perfect competition, the firm is producing where MR = MC = P. Since price is $20, MR is $20. If MC is 4 times the quantity, it is producing 5 units.
A perfectly competitive firm produces the level of output at which MR=MC on the rising portion of the firm’s marginal cost curve. At that output level, it has the following costs and revenues: TC = $830,000 VC = $525,000 TR = $428,000 At that optimal level of output, what profit (loss) does the firm earn?
Will a profit-maximizing firm in a competitive market ever produce a positive level of output in the range where the marginal cost is falling? Give an explanation.
The market for drones is perfectly competitive. Assume for simplicity that fractions of everything, including firms, is possible. We have identical firms, each with a Total Cost curve of TC=712+q^2 and Marginal Cost curve MC=2q. Market demand is Q=895-2P. What is the long-run equilibrium market price? Enter a number only, drop the $ sign.
A competitive firm is maximizing its profit by selling 150 units of output. The firm’s marginal cost is $8 and its average total cost is $6. The firm’s profit amounts to what?
A firm in a perfectly competitive market has a short-run total cost function equal to SRTC=4+20q, where q is the number of units the firm produces. The firm faces a market price of $10. Enter the optimal number of units should this firm produce to profit maximize? Hint: this could be considered a "trick question", but it's easy once you think about the way a firm should profit maximize.
In the long-run equilibrium of a competitive market with identical firms, what are the relationships among price (P), marginal cost (MC), and average total cost (ATC)?
In perfect competition, each company generates a fraction of the total production so small that increasing or decreasing its production will have a perceptible influence on the total supply and the price of the product. True or false
Consider the following cost curve for a firm in a competitive industry where the market price equals $150. C= =q° + 6q + 1,500. What is the firm's marginal cost (MC)? MC = 150. (Properly format your expression using the tools in the palette. Hover over tools to see keyboard shortcuts. E.g., a superscript can be created with the ^ character.) At what level of output does the firm maximize profits (minimize losses)? Profit is maximized at 12 units of output. (Round your answer to two decimal places.) What is the firm's profit maximizing price? The profit-maximizing price is $ (Round your response to the nearest dollar.) What is the firm's profit? The firm earns a profit of $.

a) A profit-maximizing business incurs an economic loss of $10,000 per year. Its fixed cost is $15,000 per year. Should it produce or shut down in the short run? Should it stay in the industry or exit in the long run? b) Suppose instead that this business has a fixed cost of $6,000 per year. Should it produce or shut down in the short run? Should it stay in the industry or exit in the long run?
If a competitive firm has a U-shaped marginal cost curve then A) the profit maximizing output will always generate positive economic profit. B) the profit maximizing output will always generate positive producer surplus. C) the profit maximizing output is found where MC = MR and MC is decreasing. D) the profit maximizing output is found where MC = MR and MC is constant. E) the profit maximizing output is found where MC = MR and MC is increasing.
