derive an expression for teddy's profit function

Explain in detail how a perfectly competitive firm makes its profitmaximizing decision.

Hi, I do not understand why B is the correct answer for number 3. How do I know that this monoply is earning a normal economic profit in the long run?

Can you explain the ( Compare the values ) part and how Q = 6.5 is profit maximized?

q 0 1 2 345 6 7 8 9 10 tr 30 58 84 108 130 150 168 184 198 210 tc 10 23 30 41 56 75 98 125 156 191 230 profit -10 7 28 43 52 55 52 43 28 7 -30

WHAT IS HIS PROFIT

When would a profit-maximizing firm shut down in the short run?

Hi, where is P comes from? In the question, it says profit = ei - ci, how does pi*ei makes sense?

Calculate Iyana's marginal revenue and marginal cost for the first seven rompers they produce, and plot them on the following graph. Use the blue points (circle symbol) to plot marginal revenue and the orange points (square symbol) to plot marginal cost at each quantity. COSTS AND REVENUE (Dollars per romper) 40 35 30 25 20 15 10 0 0 1 2 3 4 5 6 7 8 QUANTITY (Rompers) Marginal Revenue Marginal Cost ? Iyana's profit is maximized when they produce a total of is $ , an amount rompers. At this quantity, the marginal cost of the final romper they produce than the price received for each romper they sell. At this point, the marginal cost of producing one more romper (the first romper beyond the profit maximizing quantity) is $ , an amount than the price received for each romper they sell. Therefore, Iyana's profit-maximizing quantity occurs at the point of intersection between the Because Iyana is a price taker, the previous condition is equivalent to curves.

Nathan runs a rare book store. Last year, he earned $35,000 in revenue and had explicit costs of $8,000. Nathan could have made $35,000 driving a boat in a water ski show and received an additional $5,000 if he had used the company's inputs in a different way. Calculate Nathan's economic profit. $
