Answer:
The elasticity of supply for hot cocoa calculated at 1.43.
(D) The coffee market's supply is less elastic compared to that of hot cocoa.
Explanation:
Applying the midpoint formula,
The elasticity of supply for hot cocoa is (change in quantity supplied/average quantity supplied) ÷ (change in price/average price).
The change in quantity supplied amounts to 101 - 31 = 70.
The average quantity supplied equals (101 + 31)/2 = 66.
70/66 yields 1.06.
The price change is 9.75 - 4.5 = 5.25.
The average price is (9.75 + 4.5)/2 = 7.125.
5.25 divided by 7.125 results in 0.74.
Thus, hot cocoa's elasticity of supply is 1.06 ÷ 0.74 = 1.43. The supply for hot cocoa is elastic since this value exceeds 1.
For coffee, the elasticity of supply computes to (73 - 31)/(73 + 31)/2 ÷ 0.74, which simplifies to 42/52 ÷ 0.74 = 0.81 ÷ 0.74 = 1.09. Coffee supply is regarded as elastic as well because its elasticity is above 1.
However, the supply of coffee is less elastic than that of hot cocoa since its elasticity value is lower than that for hot cocoa.
