Ms. Albero decided to make juice to serve along with the pizza at the student government party. The directions said to mix 2 scoops of powdered drink mix with a half gallon of water to make each pitcher of juice. One of ms. Albero’s students said she will mix 8 scoops with 2 gallons of water to make 4 pitchers. How can you use the concept of proportual relationship to decide whether the student is correct?
