If these are the only four buyers in the market, then the market quantity demanded at a price of $1 is

A binding price ceiling may not help all consumers, but it does not hurt any consumers.

Refer to Figure 4-30. In this market for iPhones, the technology improves while all other factors remain constant. Which curve(s) shift(s) and in which direction?

The producer surplus for the producers entering the market after the price increase is
Refer to Figure 4-15. Which of the following would cause the supply curve to shift from Supply A to Supply C in the market for beach towels?

When a binding price floor is imposed on a market to benefit sellers,
some sellers benefit, and some sellers are harmed.
Last month, sellers of good Y took in $100 in total revenue on sales of 50 units of good Y. This month sellers of good Y raised their price and took in $120 in total revenue on sales of 40 units of good Y. At the same time, the price of good X stayed the same, but sales of good X increased from 20 units to 40 units. We can conclude that goods X and Y are
substitutes, and have a cross-price elasticity of 1.67.
Suppose roses are currently selling for $40 per dozen, but the equilibrium price of roses is $30 per dozen. We would expect a
surplus to exist and the market price of roses to decrease
Suppose buyers, rather than sellers, were required to pay this tax (in the same amount per unit as shown in the graph). Relative to the tax on sellers, the tax on buyers would result in
the same amount of tax revenue for the government
If buyers and sellers in a certain market are price takers, then individually
they have no influence on market price
