Question

A corn refining company produces corn gluten cattle feed at a variable cost of $82 per ton. If fixed costs are $120 000 per month and the feed sells for $134 per ton, how many tonnes must be sold each month for the company to have a monthly profit of $560 000?

Answer 1

C(x) = 82x - 120000
R(x) = 134x

P(x) = R(x) - C(x); then derive and maximize

Answer 2

.. its not a max problem :)

560000 = R(x) - C(x)
