Answer:
The correct answer is option a.
Explanation:
The price elasticity of demand for tickets to a baseball game is 0.89. This means that the demand is relatively inelastic.
Relatively inelastic demand means that a change in price will lead to a less than proportionate change in quantity demanded.
So at this point, if the price of tickets is increased, the decrease in price will be less than proportionate. This will lead to an increase in revenue and hence profits.
So to increase the revenue price of tickets should be increased.
