5. Suppose we have a mini-economy with only three resources, which are in the form of fields of grain. They produce as follows: Corn or Oats Field A 100 100 Field B 50 100 Field C 50 125
a) If all three fields are used to produce corn, how much corn can this little economy produce? How much oats will it produce if all three fields are used to produce corn? (Hint: This is meant to be as simple as it looks.)
b) If all three fields are used to produce oats, how much corn will this little economy produce? How much oats will be produced?
c) In parts a and b you computed two of the points on the production-possibilities frontier. Now compute the other two and fill in the four points of the production possibilities frontier below.
	Corn	Oats
		0
d) Is the point 100 corn and 200 oats possible? ?? Yes No
e) Is the point 200 corn and 100 oats possible? ?? Yes No
f) If field B is left empty, what happens to the production-possibilities frontier? ?? It shifts in. It shifts out. It does not change.
