Answer: Set a lower price in the market that is more price elastic.
Step-by-step explanation:
It would be in the best interest of the firm with market power to set a lower price if the market is more price elastic.
Price elasticity is the measure of how much quantity demanded changes in response to a change in price.
If the firm with market power sets a lower price in a market that is more price elastic, it can expect that the quantity demanded will increase more which can give a higher profit.
