Answer:
If the elasticity of demand of golf balls sold in the US is -0.4, the new equilibrium price will be -37.5% less price
Explanation:
In order to calculate the new equilibrium price If the elasticity of demand of golf balls sold in the US is -0.4 we would have to use the following formula:
Price elasticity of demand= percentage change in quantity demanded /percentage change in price of the good
According to the given data we have the following:
Price elasticity of demand=-0.4
percentage change in quantity demanded=15%
Therefore, -0.4=15%/percentage change in price of the good
percentage change in price of the good=15%/-04
percentage change in price of the good=-37.5%
Therefore, If the elasticity of demand of golf balls sold in the US is -0.4, the new equilibrium price will be -37.5% less price
