Expert Solution
Step 1
Price elasticity can be divided into:
1. Perfectly elastic demand: When a small change in price causes an infinite change in the quantity demanded, the demand is said to be perfectly elastic.
2. Elastic demand: When the price changes less than the quantity demanded, the demand is said to be elastic.
3. Inelastic demand: When price changes more than the quantity demanded, demand is said to be inelastic.
4. Perfectly Inelastic Demand: When a small change in price has no effect on the quantity demanded, the demand is said to be perfectly elastic.
5. Unitary elastic: When a change in price equals a change in quantity demanded, the demand is said to be elastic.
