Maggie switched the money on Marius by replacing the packs of $100 bills with one $100 bill in front and back of each pack and $1 bills in between. If each pack would've had 100 $100 bills, then they had 1,100 packs. Her packs contained $298. 1,100 packs of $298 equals $327,800. She had to have prepared them without the money from the wall; she didn't have time to get the money from the wall, take it to a bank to get so many $1 bills, wrap them to look like the real bundles, and get it done before Marius got there. Where did Maggie get all of those $1 bills? She would need 107,800 $1 bills.
