A retail store faces a demand equation for Roller Blades given by: Q= 180-1.5P where Q is the number of pairs sold per month and P is the price per pair in dollars.
a. The store currently charges P =$80 per pair. At this price, determine the number of pairs sold.
b. If management were to raise the price to $100, what would be the impact on pairs sold? On the store's revenue from Roller Blades?
c. Compute the point elasticity of demand first at P =$80, then at P =$100. At which price is demand more price sensitive?
