Country Leagsville can only produce Steel and Food with the given amount of resources and technology. The Production Possibilities are given below:

Combination	Steel (Tonnes)	Food (Tonnes)
A	0	100
B	25	90
C	50	70
D	75	40
E	100	0

1. Draw the Production Possibilities Curve?
2. Calculate the Opportunity Cost of moving from Combination C to D
3. How does this illustrate Increasing Opportunity Cost?

Suppose the 'Economic Growth' allows us to produce more goods, so that the new production possibilities for Steel and Food are as follows:

Combination	Steel (Tonnes)	Food (Tonnes)
A	0	100
B	25	90
C	50	70
D	75	60
E	100	40
F	125	0

1. Draw the new Production Possibilities Curve, and describe how the New Curve is related to the Old curve.
