Final answer:
The pricing difference indicates that demand is more elastic in market X than market Y.
Step-by-step explanation:
The pricing difference indicates that demand is relatively more elastic in market X than market Y.
In market X, the price-discriminating pure monopoly charges a higher price because demand is more elastic. This means that a small change in price will cause a larger change in quantity demanded. In market Y, the lower price suggests that demand is relatively less elastic. Here, a change in price will not have as significant of an impact on quantity demanded.
Overall, the pricing difference reflects the different elasticities of demand in each market.
