Answer:
The elasticity of supply for hot cocoa is 1.43.
(D) Supply in the market for coffee is less elastic than supply in the market for hot cocoa
Explanation:
Using the midpoint formula,
Elasticity of supply for hot cocoa = (change in quantity supplied/average quantity supplied) ÷ (change in price/average price)
change in quantity supplied = 101 - 31 = 70
average quantity supplied = (101+31)/2 = 66
70/66 = 1.06
change in price = 9.75 - 4.5 = 5.25
average price = (9.75+4.5)/2 = 7.125
5.25/7.125 = 0.74
Elasticity of supply for hot cocoa = 1.06 ÷ 0.74 = 1.43. The supply for hot cocoa is elastic because the elasticity of supply is greater than 1.
Elasticity of supply for coffee = (73 - 31)/(73+31)/2 ÷ 0.74 = 42/52 ÷ 0.74 = 0.81 ÷ 0.74 = 1.09. The supply for coffee is elastic because the elasticity of supply is greater than 1.
However, supply in the market for coffee is less elastic than supply in the market for hot cocoa because the elasticity of supply for coffee is less than that of hot coffee.
