Suppose a new manufacturing technology results in an expansion in the supply of golf balls in the United States of 15%. If the elasticity of demand of golf balls sold in the US is - 0.4, the new equilibrium price will be

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
