Answer:
a 10% increase in price will reduce the demand and total expenditures on good X by 5%.
Explanation:
Price elasticity of demand(PED) is the degree of responsiveness of demand to a change in price.
Where a percentage change in price produces a more than a proportional change in quantity, we say the product is price elastic. On the other hand, where a change in price produces a less than a proportional change in quantity demand, then demand is price inelastic
PED is computed as follows:
PED = % change in quantity /% change in Price
So we can apply this formula to this question
0.5 = m/10
m = 0.5 × 10
m = 5.
m= 5%
From the computation above , it is deduced that a 10% increase in price will reduce the demand and total expenditures on good X by 5%.
