Answer: Price reduced by 2%
Explanation:
The price elasticity of demand shows how the demand for a good will change as a result of a change in price. Demand will usually increase as a result of a decrease in price because people tend to demand more when goods are cheaper.
The formula is;
Price elasticity of demand = ΔQuantity demanded / Δ Price
-5 = 10% / P
-5P = 10%
ΔP = -2%
