 * ====== Big Idea:   Many important practical and mathematical applications involve comparing quantities of one kind or another; it is important to know which method to use and how we should use them.   ======
 * Essential Question: __//    What methods are there for comparing things?    //__
 * Notes from Class:


 * Write an equation relating the cost**(c) **and the number of bead (x) for each type of bead:**

Spheres: c= .6 OR 12 cents times every 20 beads Cubes: c= .8 OR 12 cents times every 15 beads Cylinders: c= .08 OR 8 cents times every 10 beads

__Follow-Up__


 * For each type of bead, you could find two unit rates. You could find the # of beads for each unit cost ( in other words, for each cent), and you could find the cost for each bead.**

if I were trying yo do this,then the rate that would be used would be the rate that tells us exactly the amount of set amount of money needed for the set amount of beads.
 * 1) **Which Unit Rate would be most useful if you were trying to figure out the number of beads you could buy with the certain amount of money?**


 * 2. Which unit rate would be most useful if you were trying to figure out how much money a certain number of beads cost?**

The unit rate that would be used would be the rate that tells us the exact amount of money needed for 1 bead each.
