DAY 192
Tom S. Windler had $5.00, but he needed $6 to buy a baseball glove. He went to a pawnshop and pawned his $5 bill for $4. Next he sold his pawn ticket to Jerry for $2. Tom then had enough to buy the glove. Who lost on this deal and how much?

Answer:

Jerry lost $1. He had to pay $4 to redeem the $5 bill, and he had already given Tom $2 (not including any service fee which might be charged by the pawnbroker).
