19. A recipe that yields 2 loaves of bread requires 3½ cups of sugar. You have a bag of sugar that contains 14¼ cups. How many cups of sugar will be left in the bag if you make 8 loaves of bread? 8 loaves ÷ 2 loaves per batch = 4 batches 4 batches ∙ 3 ½ cups of sugar = 14 cups 14¼ cups – 14 cups for recipe = ¼ cup left over.
