12) At price of $1.30 per pound, a local apple orchard is willing to supply 150 pounds

13) Figure 17-2. Two companies, Acme and Pinnacle, each decide whether to produce
a good quality product or a poor quality product. In the figure, the dollar amounts are
payoffs and they represent annual profits for the two companies.

profit. If this game is played repeatedly and Acme uses a tit-for-tat strategy, it will
choose a

whatever Pinnacle chose in the previous round.
c.good quality product in all rounds, regardless of the choice made by Pinnacle.
