Answer:
Government should increase the price by $1
Explanation:
Use Price elasticity formula to calculate the percentage change in price.
Price elasticity = % Change in demand / %Change in price
- 0.4 = 20% / %Change in price
%Change in price= - 20% / 0.4
%Change in price= - 50%
So the government has to increase the price by 50%.
Current Price = $2
Increase in Price = $2 x 50% = $1
