• Step 1.) Read the client order. A sample client order might read "I have a five quarters three dimes, three nickels and five pennies, please change this money using the smallest number of coins possible". Calculate the total amouont of change the customer has ($1.75). Next, think of a way to make $1.75 with as few coins as possible (one dollar coin, one half dollar, one quarter).
• Step 2.) Drag the coins into the piggy bank one at a time
• Step 3.) Click "send". If you are a good changer, you will earn a portion of the customer's change!
