For the first time in two years, Big G (the cereal division of General Mills) raisedcereal prices by 4 percent. If, as a result of this price increase, the volume of all cerealsold by Big G dropped by 5 percent, what can you infer about the own price elasticityof demand for Big G cereal? Can you predict whether revenues on sales of its LuckyCharms brand increased or decreased? Explain. (LO1, LO3)
**Asking for part (d) only**
Suppose the demand for crossing the Golden Gate Bridge is given by Q = 10,000 − 1,000P. (LO6)
a. If the toll (P) is $3, how much revenue is collected?
b. What is the price elasticity of demand at this point?
c. Could the bridge authorities increase their revenues
by changing their price?
d. In 2019, the San Francisco Bay area Water Emer-
gency Transportation Authority (WETA) announced it was considering the implementation of hovercraft service as a supplement to existing ferries. Suppose that a fast hovercraft alternative to the Golden Gate Bridge is implemented between Marin County and San Francisco. How would the new service affect the elasticity of demand for trips across the Golden Gate Bridge?
Suppose demand and supply are given by: (LO3, LO4)Qx d = 14 − 1/2Px and Qx s = 1/4Px − 1a. Determine the equilibrium price and quantity.

Suppose that annual demand in the U.S. market for ice cream cones can be expressed as QD = 800 + .2I - 100P, where QD is the number of cones demanded in millions of cones, I equals average monthly income in dollars, and P is price in dollars per cone. Supply can be expressed as QS = 200 + 150P (with the same units for quantity and price). A. Graph the demand and supply curves for ice cream cones, assuming that average monthly income is $2,000, and solve for the equilibrium price and quantity. B. Now assume that average monthly income drops to $750 and supply is unchanged. Draw the new demand curve on the same graph as used in (a) above and solve for the new equilibrium price and quantity.
