How would a canal help farmers grow more wheat?

Need help with math homework?

• A farmer has 1200 acres of land on which he grows corn, wheat, and soybeans. It costs $45 per acre to grow corn, $60 to grow wheat, and $50 to grow soybeans. Because of market demand the farmer will grow twice as many acres of wheat as of corn. He has allocated $63,750 for the cost of growing his crops. How many acres of each crop should he plant? I just need help finding the equations for this. I've come up with 2 and I think I need 3. I'm not even sure if I got the first two equations right. Are they right and if not what is the right equation(s)? What's the third equation? Thanks x+y+z=1200 45x+60y+50z=63,750 x=corn y=wheat z=soybeans

• Answer:

  The first two are right. You're missing 2x = y.
