Scenario 16-4
Peter Operates an Ice Cream Shop in the Center

Scenario 16-4
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.)
$\begin{array}{|l|l|l|l|l|}\hline \text { Quantity } & \text { Price } & \text { MR } & \text { MC } & \text { ATC } \\\hline 20 & \$ 5.60 & \$ 5.20 & \$ 2.20 & \$ 2.05 \\\hline 40 & \$ 5.20 & \$ 4.40 & \$ 2.40 & \$ 2.10 \\\hline 60 & \$ 4.80 & \$ 3.60 & \$ 2.60 & \$ 2.15 \\\hline 80 & \$ 4.40 & \$ 2.80 & \$ 2.80 & \$ 2.20 \\\hline 100 & \$ 4.00 & \$ 2.00 & \$ 3.00 & \$ 2.25 \\\hline 120 & \$ 3.60 & \$ 1.20 & \$ 3.20 & \$ 2.30 \\\hline 140 & \$ 3.20 & \$ 0.40 & \$ 3.40 & \$ 2.35 \\\hline 160 & \$ 2.80 & -\$ 0.40 & \$ 3.60 & \$ 2.40 \\\hline 180 & \$ 2.40 & -\$ 1.20 & \$ 3.80 & \$ 2.45 \\\hline\end{array}$
