Sharon is a skilled toy maker who is able to produce both trains and balls. She has 8 hours a day to produce toys. The following table shows the daily output resulting from various possible combinations of her time.
Choice
Hours Producing
Produced
(Trains)
(Balls)
(Trains)
(Balls)
A 8 0 4 0
B 6 2 3 11
C 4 4 2 15
D 2 6 1 18
E 0 8 0 19

On the following graph, use the blue points (circle symbol) to plot Sharon's initial production possibilities frontier (PPF).

Suppose Sharon buys a new tool that enables her to produce twice as many trains per hour as before, but it doesn't affect her ability to produce balls. Use the green points (triangle symbol) to plot her new PPF on the previous graph.

Because she can now make more trains per hour, Sharon's opportunity cost of producing balls is ____________ it was previously.

## Expert Answer

Step 1

Begin with plotting the initial PPF using the table that shows production of trains and balls.

Our co-ordinates as per the table are  (4,0), (3,11), (2,15), (1,18), (0,19) which are marked by black circles (excuse my freehand) in the image below. A line through these co-ordinates would give you the initial PPF curve.

Step 2

If the production of trains doubles, our new co-ordinates would be (8,0), (6,11), (4...
