Scenario 16-3
Peter operates an ice cream shop in the center of Fairfield. He sells several unusual flavors of organic, homemade ice
cream so he has a monopoly over his own ice cream, though he competes with many other firms selling ice cream in
Fairfield for the same customers. Peter’s demand and cost values for sales per day are given in the table below. (Everyone
who purchases Peter’s ice cream buys a double scoop cone because it’s so delicious.)
