Jerry's mom is going on a trip this weekend, so she has to pack a suitcase. She asks Jerry to help her.  Jerry has never done this before, so he sits down on the bed near his mom and asks her what to do.  She says,  "Wait here while I pick out my clothes I will bring." She jumps up and reaches for the dresser.  She opens up the drawers and picks some nice clothes to wear on her trip.  She will also need things like shoes, and toothpaste, shampoo and soap.  So, she has a separate bag for those things, and once it is filled up she puts the clothes in her big bag with Jerry's help.She puts her smaller bag with her soap and toothpaste, into the big bag last. She makes everything really neat and tidy in the bag, and then closes the bag up with the zipper. She puts the bag near the door so that she knows where it is when it is time to go. 
Question: How many suitcases were packed?
