cups of frozen lemonade concentrate for every 7 cups of water.
• Using Granny’s recipe, how many cups of lemonade will be

Suppose Noah wants to make only 1 cup of lemonade. How much frozen
lemonade concentrate would he need using Granny’s recipe? How much frozen
lemonade concentrate would he need using Mom’s recipe? Explain how you got
your answers.
On the grid below, draw line graphs for the amount of water and
frozen lemonade concentrate for Granny’s recipe and Mom’s
recipe.

11.
As the amount of frozen lemonade concentrate increases, do the graphs seem to be
farther apart or closer together?
Noah has decided to change Mom’s recipe, decreasing the amount
of frozen lemonade concentrate and keeping the same amount of
water. What effect will this have on the graph? Will the
lemonade taste stronger, weaker, or the same? Explain your
answer.
12.
What if Noah kept the amount of frozen lemonade concentrate the same as Mom’s
original recipe, but decreased the amount of water. What effect will this have on
the graph? Does the lemonade taste stronger, weaker, or the same? Explain your
answer.
13.
What if Noah decreased both the amount of frozen lemonade concentrate and the
amount of water? What effect will this have on the graph? Does the lemonade
taste stronger, weaker, or the same? Explain your answer.
