Answer #1

Price elasticity of demand tells us how much demand for a good will change due to change in the price of the good.

Formula:

Price elasticity of demand = % change in demand / % change in price

Given, the price elasticity of demand = - 3.7 , Increase in price = + 7%

Putting the above values in the formula we will get,

- 3.7 = % change in demand / +7%

% change in demand = - 25.9%

So, when the price of good increases by 7% then the demand for the good will decrease by 25.9%.
