Final answer:
To increase tee time sales by 10% with a price elasticity of demand at -1.5, prices should be decreased by 6.67%.
Step-by-step explanation:
To answer how much the price of a tee time should be changed to increase sales by the desired 10%, we use the price elasticity of demand, which is given as -1.5. Since the elasticity is higher than 1 in absolute value (elastic demand), according to the provided reference, a decrease in price will lead to a proportionally larger increase in the amount sold, which increases total revenue.
We can use the formula for percentage change in quantity demanded:
Percentage change in quantity demanded = (Percentage change in price) × Price Elasticity of Demand
To increase sales by 10%, we set the percentage change in quantity demanded to 10 and solve for the percentage change in price:
10 = (Percentage change in price) × (-1.5)
Percentage change in price = 10 / (-1.5) = -6.67%
Therefore, to increase the number of tee times sold by 10%, the price should be decreased by 6.67%.
