I have this idea in my head. I want my students to compare two products and tell us which one to buy and why. I would like to model the end product that I'm looking for and I'll use soda stream as my example. The big question will be "Should I buy the soda stream or continue to drink name brand soda products?" I will consider things like cost, convenience, the environment, quality, etc. The big math part of this will be writing two linear equations (one for each product), making a table, and graphing the equations, to determine which is the better price at varying levels.
But that's where I'm stuck. I want to create a list of products for my students to choose from, but I'm not coming up with a lot of ideas. Help!!
My thoughts so far:
K-cups vs. regular brewing. (I'm thinking the lines for this would not intersect in the 1st quadrant.)
Dishwasher vs. hand-washing?????
e-reader vs. traditional book.
