Air fares are generally lower on Tuesdays and Wednesdays each week. What is a likely explanation for this occurrence? Supply is relatively variable, and lower demand on these days leads to a lower equilibrium price. Demand is relatively variable, and lower supply leads to a lower equilibrium price. O Lower levels of both supply and demand on these days lead to a lower equilibrium price. O Supply is relatively fixed, and lower demand on these days leads to a lower equilibrium price. Demand is relatively fixed, and lower supply leads to a lower equilibrium price.

Suppose an economic boom causes incomes to increase and, at the same time, drives up wages for the sales representatives who work for cell phone companies. Assume that smartphones are a normal good. This will cause the: O price of cell phones and the equilibrium quantity to rise. O price of cell phones to rise, but the change in the equilibrium quantity is unclear and depends on whether the shift in demand is larger or smaller than the shift in supply. O price of cell phones and the equilibrium quantity to fall. O quantity of cell phones to rise, but the change in the equilibrium price is unclear and depends on whether the shift in demand is larger or smaller than the shift in supply.
