Marco came to a drawbridge that had a sign stating that the tolltaker would double his money each time he crossed the bridge, but Marco would have to paya fee of $1.20 per crossing. Marco decided he would cross the bridge 3 times, tosee how the system worked.

Sure enough, each time Marco crossed the bridge the toll takerdoubled the amount of money in Marco's pocket and then took his $1.20 toll charge. Marcowas surprised when , after the third crossing, he paid the $1.20fee and found himself with no money.
