Solution
The midpoint formula is calculated first for the percentage change in price and then for the percentage change in quantity.
Percentage change in price = (New price – Old price) / (average price)
= (10.75 – 3.50) / ((10.75 + 3.50) / 2) = 101.75%
Percentage change in quantity = (New quantity – Old quantity) / (average quantity)
= (109 – 29) / ((109 + 29) / 2) = 115.94%
Elasticity of supply for hot cocoa = 101.75 / 115.94 = 0.88
The change in price for both the products is the same however, the change in the quantity supplied for coffee is less than the change in the quantity supplied for hot cocoa. Hence it can be said that the supply in the market for coffee is less elastic than supply in the market for hot cocoa.
