Answer:
The demand for Post Raisin Brand cereal is: ELASTIC
the demand for all types of breakfast cereals is: INELASTIC
Step-by-step explanation:
To calculate the price elasticity of demand (PED) we can use the following formula:
PED = % change in quantity / % change in price
- If PED > 1, the demand is price elastic
- If PED = 1, the demand is price unitary
- If PED < 1, the demand is price inelastic
*The PED always results in a negative number, e.g. price deceases, quantity increases, but for practical reasons we convert the negative number into a positive (we use absolute values) when we are determining the elasticity.
