Suppose that you own a 10-acre plot of land that you would like to rent out to wheat farmers. For them, bringing in a harvest involves $30 per acre for seed, $80 per acre for fertilizer, and $70 per acre for equipment rentals and labor. With these inputs, the land will yield 40 bushels of wheat per acre.
If the price at which wheat can be sold is $5 per bushel and if farmers want to earn a normal profit of $10 per acre, what is the most that any farmer would pay to rent your 10 acres?
What if the price of wheat rose to $6 per bushel?
