Answer: ____________Jada discovers another smoothie store called Samara’s Smoothies. Sadia uses the same ratio for all of her smoothies. Samara’s ratios are different than Sadia’s, which makes the strength of the blueberry flavor in their smoothies different from each other. Samara uses 3 ounces of blueberries for every 6 ounces of yogurt, which makes 9 ounces of smoothie.
Who makes the blueberry smoothie with the strongest flavor, Sadia or Samara?
