Answer:
perfectly inelastic
Step-by-step explanation:
This rule would cause the price elasticity to become perfectly inelastic. This is because there is a limited amount of dormitories available and the school has not mentioned adding more, therefore making the quantity finite. Since the rule forces students to need a dormitory, this would make the price rise as more and more dormitories become taken. Meaning that the rise in price plus the stable and constant quantity makes the elasticity perfectly inelastic.
