The sandwich shop is a restaurant that serves only one item, the ham sandwich. The restaurant serves two groups of customers, younger adults and senior citizens. The two segments have the following demand functions: younger adults, Qy = 5,000 – 10Py and senior citizens, Qs = 10,000 – 100Ps. The restaurant has constant marginal cost of $10 and no fixed costs.

(4)a. Write the inverse demand and marginal revenue functions for each segment of the ham sandwich market.

(4)b. What are the profit maximizing price and quantity for each segment and how much profit will he earn?

(4)c. What are the price elasticities of demand for each segment at the prices and quantities you determined in part “b”

Suppose you own a sandwich shop with fixed costs of $1,000/month and marginal costs of $2.00/sandwich. If the price is $6/sandwich, 500 sandwiches are sold. If the price is $4.50/sandwich, 800 sandwiches are sold. A)  Use these figures to calculate the price elasticity. B) Calculate the profits and profit margins (profit/total cost) associated with the price at $6/sandwich and at $4.50/sandwich. Given these calculations, what price should you charge for sandwiches?
