o you like smoothies? Perhaps one of the best things about smoothies is that
you can make one with just about any ingredients. Just throw them in the blender
and turn it on!
Smoothies can be very healthy too. Try this healthy smoothie recipe sometime.

Problem 1
May the Best Recipe Win
Each year, your class presents its mathematics portfolio to parents and community
members. This year, your homeroom is in charge of the refreshments for the reception that
follows the presentations. Four students in the class give their recipes for punch. The
class wants to analyze the recipes to determine which will make the punch with the
strongest grapefruit flavor, and which will make the strongest lemon-lime soda flavor.
The recipes are shown.
Bobbi’sRecipe
Adam’sRecipe
4 parts lemon-lime soda
3 parts lemon-lime soda
8 parts grapefruit juice
5 parts grapefruit juice
Zeb’sRecipe
Carlos’sRecipe
2 parts lemon-lime soda
1 part lemon-lime soda
3 parts grapefruit juice
4 parts grapefruit juice
1.How many total parts are in each person’s recipe?
2.For each recipe, write a ratio that compares the number of parts of grapefruit juice to
the total number of parts in each recipe. If possible, simplify each rate.

Problem 2
Making the Refreshments
1.You are borrowing glasses from the cafeteria to serve the punch. Each glass holds
6 fluid ounces of punch. Your class expects that 70 students and 90 parents and
community members will attend the reception. You decide to make enough punch so
that every person who attends can have one glass of punch. How many fluid ounces
of punch will you need for the reception?
Previously, you wrote rates to compare parts of each ingredient to total parts of all the
ingredients. Recall that a rate is a ratio in which the units of the parts or the whole being
compared are different.
2.Determine the unit rate for the fluid ounces of punch there would be in one part of the
recipe if your class uses Adam’s recipe.
3.How many fluid ounces of lemon-lime soda and grapefruit juice are needed to make

grapefruit flavor? How does the table confirm your choice?

9.In Problem 1, Question 5 you determined which recipe would have the strongest
lemon-lime soda flavor? How does the table confirm your choice?
10. If you would use 8-ounce glasses for the reception rather than 6-ounce glasses, how
would that affect the amount of punch you would need to make?

11. Will the ratio of the parts for any of the recipes change by putting more punch in each
glass? Explain your reasoning.
