From the table above, Calculate the price elasticity of supply
The correct answer is: B
Explanation
The elasticity of supply = % change in quantity supplied /%change in price
First, we calculate the individual change in supply and price. hence we have:
For supply we have: βQs/Old Qs x 100
=(24 - 20 )/20 x 100
=4/20 x 100
=20%
For price we have: βP/Old price x 100
=(10 - 8 )/8 x 100
=2/8 x 100
=25%
%βQs/%βprice
=20/25
=0.8
