Shake Mix A for $23
Shake Mix B for $110?
Whichever answer you choose, justify your reasoning with mathematics.

There are plenty of examples of protein shake labels on the Internet. I would be encouraged to make this a part of a lesson that analyzes nutrition labels, regardless of whether or not my students were drinking protein shakes. There is a HUGE market for them and students certainly know someone who is enamored with shakes for one reason or another.
