Answer:
a. - 0.5%
b. Raise
Explanation:
In this question we apply the price elasticity of demand formula i.e shown in the question
The formula to compute the Price elasticity of demand is shown below:
Price elasticity of demand = (Percentage change in quantity demanded) ÷ (percentage change in price)
= 5% ÷ -10%
= - 0.5%
As we can see that the demand is inelastic that means if the price change of a particular good than there is no effect in the demand
b. So in this case, the company should raise the product price
