PART II: MATH COMPUTATIONS A farmer collects 18 bushels of grain x bushels are used for feed and y bushels are sold to companies. The farmer produces 330 pounds, unequally split up between feed and the companies. Feed: 20 quarts per bushel Companies: 15 quarts per bushel Write an equation for total bushels. 15x+20y=330 is almost a correct equation for total pounds. Please fix it. Think about the system formed by your two equations above. Which method (substitution, elimination, or graph) will you use to solve it? Why?
