In the Boutique Shop, you must determine the change a customer receives from $5.00 for each purchase and decide what coins you use to make the change.  You have quarters, dimes, nickels, and pennies.

• List all the different ways you can make change in this problem?

• What is the least number of coins you need to find this change? 

• Whats the most number of coins you can use to find this change if you have a limit of 9 of any particular coin? 

• Why can you use only 8 pennies or 3 pennies? (Why not 9, 7, 6, 5, 4, 2, 1, or 0?)
