In size 6, a pair of Nike Free Runs costs $100. In Size 8? $100. Size 11? $100, again. Is this fair? After all, people with small feet are paying the same as people with big feet, but they're getting less shoe!
In this lesson students will calculate unit rates to determine how much different sized shoes cost per ounce. They'll then use the unit rate to solve proportions to find out how much shoes would cost if Nike decided to charge by weight, and will discuss whether they should!
