Answer:
a. Smoking might decline by 7.2%
b. Teen smoking would decline by 12.6%
Step-by-step explanation:
1. The elasticity of demand is able to check the amount that demand will reduce by if prices rose.
The formula is;
= % change in quantity demanded / % change in price
Given that a 10% price increase reduced cigarette consumption about 4% in the past, the elasticity is;
= -4%/10%
= - 0.4
Given that prices rise by 18%, the resultant decrease in consumption should be;
= - 0.4 * 18%
= -7.2%
b. Given and elasticity of demand of 0.7, the teen smoking rate would decline by;
= elasticity * price increase
= 0.7 * 0.18
= 12.6%
