In the following table, which contains the demand schedule for a monopolist, enter the total revenue (TR) and marginal revenue (MR) for each price. For each price-quantity combination (that is, table row), indicate whether demand is elastic, unitary elastic, or inelastic at that point on the demand curve.

Hint: Do not calculate the price elasticity of demand mathematically. Instead, use what you know about elasticity along different segments of a linear demand curve to determine the elasticity of each price-quantity combination.
