Suppose pigs (P) can be fed corn-based feed (C) or soybean-based feed (S) such that the production function is P = 2C + 5S. If the price of corn feed is $2 and the price of soybean feed is $6, what is the cost-minimizing fee combination producing P = 200?

a.

C = 100

b.

S = 40

c.

C = 50, S = 20

d.

All points on the P = 200 isoquant would cost the same.
