Suppose the market demand for pizza is given by Q_d = 300 - 20_P and the market supply for pizza is given by Q_s = 20_P - 100, where P = price (per pizza).
a. Graph the supply and demand schedules for pizza using $5 through $15 as the value of P.
b. In equilibrium, how many pizzas would be sold and at what price?
c. What would happen if suppliers set the price of pizza at $15? Explain the market adjustment process.
d. Suppose the price of hamburgers, a substitute for pizza, doubles. This leads to a doubling of the demand for pizza. (At each price, consumers demand twice as much pizza as before.) Write the equation for the new market demand for pizza.
e. Find the new equilibrium price and quantity of pizza.
