Question 1

Suppose the number of firms you compete with has recently increased. You estimated that as a result of the increased competition, the demand elasticity has increased from 2 to 3, i.e., you face more elastic demand. You are currently charging \$10 for your product. If demand elasticity is -3, you should charge [x].

Question 2

An amusement park, whose customer set is made up of two markets, adults and children, has developed demand schedules as follows:

The marginal operating cost of each unit of quantity is \$5. Because marginal cost is a constant, so is average variable cost.  Ignore fixed costs. The owners of the amusement part want to maximize profits.
