A farmer sells his corn for $220 a metric ton with a small surcharge of $15. His neighbour sells her corn crop for $220 a metric ton and gives a $20 rebate. Write the cost model equations for both farmers and find the amount of corn that makes the costs equal. Write the cost model equations for the first farmer. Use x to represent the number of tons. The variable C represents the total cost. C=
