Problem 1

Suppose that the total revenue received by a company selling basketballs is $\$ 600$ when the price is set at $\$ 30$ per basketball and $\$ 600$ when the price is set at $\$ 20$ per basketball. Without using the midpoint formula, can you tell whether demand is elastic, inelastic, or unit-elastic over this price range?

In $2006,$ Willem de Kooning's abstract painting Woman III sold for $\$ 137.5$ million. Portray this sale in a demand and supply diagram and comment on the elasticity of supply. Comedian George Carlin once mused, "If a painting can be forged well enough to fool some experts, why is the original so valuable?" Provide an answer.
