BOATS PER DAY
Suppose Yvette is currently using combination D, producing one boat per day. Her opportunity cost of producing a second boat per day is
per day.
Now, suppose Yvette is currently using combination C, producing two boats per day. Her opportunity cost of producing a third boat per day is
per day.
From the previous analysis, you can determine that as Yvette increases her production of boats, her opportunity cost of producing one more boat
Suppose Yvette buys a new tool that allows her to produce tvice as many boats per hour as before but doesn't affect her ability to produce balls. Use
the green points (triangle symbol) to plot her new PPC on the previous graph.
Because she can now make more boats per hour, Yvette's opportunity cost of producing balls is
it was previously.
