Economics

cupcake store is located in a mall and is the only cupcake store in that mall. The demand schedule for cupcakes (per dozen) is given in the table below. If the marginal cost to produce a dozen cupcakes is $4 per unit, how many units should the firm produce?

What price should the cupcake store charge?

If the fixed cost for the firm is $100 per day, how much profit will the firm make in one day?

What is the price elasticity of demand at the optimal price/quantity combination (use the next lower price level as the second point in your calculation)?

Is the formula for finding the correct level of output in the middle of page 74 in your text satisfied? (Note there is a typo in the text; the equation should read (P-MC)/P > 1/|e|. )

Scenario 2 (length: as needed)

A restaurant/bar is analyzing its pricing of beer. It has determined that the price elasticity of demand for beer is −0.8; the cross-price elasticity for wine with respect to the price of beer is 0.9; the cross-price elasticity for appetizers is -1.4; and the cross-price elasticity for entrees is -2.2. The current average price of a beer at this bar is $4.50, and the restaurant sells 250 pints of beer a night. The price of wine averages $8 a glass, and on a typical night 40 glasses of wine are purchased. An appetizer is priced at an average price of $6, and an entree costs $12 on average. The average number of appetizers and entrees sold per night is 70 and 25, respectively. The marginal cost of a pint of beer is $2; an additional glass of wine sold increases costs by $5; an appetizer increases costs by $4; and an entree has a marginal cost of $7. The restaurant is considering lowering the price of beer to $4.
