Ms. Freeman 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. Freeman’s students said she will mix 8 scoops with 2 gallons of water to make 4 pitchers. How can you use the concept of proportional relationships to decide whether the student is correct?

well you know that 2 scoops is for half a gallon. so that means that it is 4 scoops for a gallon. Assuming the pitchers can contain half a gallon she will need 2 gallons of water for 4 pitchers. and knowing that it is 4 scoops a gallon and you need two gallons (4*2=8) so you need 8 scoops so yes the student is correct.
Hope this helps! good luck :)

Answer:

As long as the amount of water is proportional to the number of scoops of drink mix, then the second quantity, amount of water, can be determined by multiplying the first quantity by the same constant. In this case, if the amount of powdered drink mix is represented by , and the gallons of water are represented by , then = 1/4 x. To determine any of the measures of water, you will multiply the number of scoops by 1/4.

Enjoy :)
