Answer:
The the elasticity of demand for biscuit is <u>-0.33</u>.
Explanation:
Elasticity demand is the degree of responsiveness of quantity demanded for a commodity to a change in the price of that commodity.
The elasticity of demand for biscuit can be calculated using the following elasticity of demand formula:
Elasticity of demand = Percentage change in Qd / Percentage change in price .................. (1)
Where Qd denotes quantity demanded.
Percentage change in Qd = [(New Quantity - Old Quantity) / Old quantity] * 100 = [(200 - 300) / 300] * 100 = -33.33%
Percentage change in price = [(New price - Old price) / Old price] * 100 = [(N500 - N250) / N250] * 100 = 100%
Substituting the values into equation (1), we have:
Elasticity of demand = -33.33% / 100% = - 0.33
Therefore, the the elasticity of demand for biscuit is <u>-0.33</u>.
Note that since -0.33 in absolute term |-0.33| is less than 1, the demand for biscuit is inelastic. That is, the change in the quantity demanded for biscuit responds less than the change in its price.
