4. Solve the problem graphically. Show the graph and label corner points, and find the maximum: A manufacturer makes two types of fertilizer (one for Lawn and one for the Garden) using
chemicals A and B. Lawn fertilizer is made up of 80% of chemical A and 20% of chemical B. Garden
fertilizer is made up of 60% of chemical A and 40% of chemical B. The manufacturer requires at
least 30 tons of Lawn and at least 50 tons of Garden, and has available 100 tons of chemical A and
50 tons of chemical B. How many units of Lawn and Garden should be produced in order to
maximize the total amount of fertilizer?
