. In East Icicle, Minnesota, on the northern edge of the corn
belt, the growing season is short and the soil is poor. Corn yields
are meager unless a great deal of fertilizer is 3 used. In
Corncrib, Illinois, the land is fertile and flat and the growing
season is 20 days longer. For any given expenditure per acre, corn
yields are far greater than in East Icicle. Farmers in both places
are profit maximizers who grow corn. We deduce that:
A. Marginal costs are the same in both places
B. MarginalcostsarehigherinEastIciclethaninCorncrib
C. MorefertilizerisusedperacreinEastIciclethaninCorncrib
D. More fertilizer is used per acre in Corncrib than in East
