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.
