PROBLEM 05: Britney Spears' new perfume, Uninhibited, comes in two strengths, regular and industrial strength. Each bottle of regular strength uses 3 ounces of skunk scent and 2 ounces of buttermilk, and each bottle of industrial strength uses 8 ounces of skunk scent and 2 ounces of buttermilk. Each day, Britney has 1080 ounces of skunk scent and 420 ounces of buttermilk to be used for making perfume. If Britney makes the correct number of bottles of each strength to use up all of the available ingredients, how many bottles of industrial strength perfume will Britney make?
