document.write( "A farmer had 1200 acres of land on which he grows corn, wheat, and soybeans. It costs $45 per acre to grow corn, $60 for wheat and $50 for soybeans. Because of the market demand he will grow twice as many acres of wheat as of corn. He has allocated $63,750 for the cost of growing crops. How many acres of each crop should he plant? \n" );
