Final answer:
The correct answer is C. The absolute value of the price elasticity of demand on this airline route is less than 1.
Step-by-step explanation:
The absolute value of the price elasticity of demand on this airline route can be determined using the formula:
Elasticity = % Change in Quantity Demanded / % Change in Price
From the given information, we know that the test resulted in about the same revenue with the lower fare. This means that the demand for the airline route is likely to be inelastic, with a price elasticity of demand less than 1. Therefore, the correct option is C. less than 1.
