A young chef is considering opening his own sushi bar. To do so, he would have to quit his current job, which pays $30,000 a year, and take over a restaurant space that he owns and currently rents to his brother for $24,000 a year. His expenses at the sushi bar would be $50,000 for food and $2,000 for gas and electricity.
Suppose the sushi bar’s revenue from the first year is $120,000. What is the chef’s economics profit?
14,000
-14,000
66,000

Suppose Larry runs a small business that manufactures shirts. Assume that the market for shirts is a competitive market, and the market price is $20 per shirt.
The following graph shows Larry's total cost curve.
Use the blue points (circle symbol) to plot total revenue and the green points (triangle symbol) to plot profit for shirts quantities zero through seven (inclusive) that Larry produces.
Calculate Larry's marginal revenue and marginal cost for the first seven shirts he produces, 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.
Larry's profit is maximized when he produces
shirts. When he does this, the marginal cost of the last shirt he produces is
, which is than the price Larry receives for each shirt he sells. The marginal cost of producing an additional shirt (that is, one more shirt than would maximize his profit) is
, which is…
Briefly explain using a graph whether given statement is true or false. ‘To maximise profit, a firm should produce the quantity where the difference between marginal revenue and marginal cost is the greatest. If a firm produces more than this quantity, then the profit made on each additional unit will be falling.’

Write about an example of perfect competition (or at least a market that is very close to perfect competition). Find an example of a market that seems to be perfectly competitive. Explain how your example satisfies the four conditions necessary for perfect competition. Do sellers in the market you’ve described brand themselves to consumers? Does this support the idea that this market is perfectly competitive? Explain. Do different sellers in the market you’ve described charge different prices for their product? Does your answer support the idea that this market is perfectly competitive? Explain. Does it seem as if the example you mentioned is allocatively efficient? In other words, does the market produce enough of this good (or does it produce too much or too little)? Explain.arrow_forward
