Module 11: Direct and Inverse Variation

Blueberries (cups) Flour (cups) 2 3 4 6 6 9

A recipe for blueberry muffins calls for 2 cups of blueberries for every 3 cups of flour.

The situation above represents a proportional relationship; the number of cups of blueberries and the number of cups of flour increase multiplicatively.  In this module, you will investigate proportional relationships.  You will also investigate inversely proportional relationships.
