Logic Puzzle help?!?!


Question: Jim and Rebecca travel across the country in two cars, traveling the same route in the same direction. They stop to pay the same tolls and they pay equal amounts each time. The toll never comes to more than a dollar. Before the trip each has twenty dollars set aside just for tolls, ten dollars in bills and ten dollars in change. Jim likes to hoard change and Rebecca likes to get rid of change. So Jim always pays with a dollar bill and Rebecca pays with change. Each has to stop ten times to pay tolls. Rebecca pays her first toll with one coin, her second with two coins, her third with three coins, her fourth with four coins, etc.
Obviously Jim has more change at the end of the trip. The question is: how much more change does Jim have?


Please help?!

10 dollars more.

you said that they each stopped 10 times to pay a toll, so if rebecca paid they toll 10 times with 10 dollars worth of change, she'd have no change left and 10 bills after all 10 toll payments. jim uses bills, so after 10 toll payments, he has no bills and 10 bucks in change. so he has 10 more dollars worth. the whole "rebecca uses one coin, then two, etc." is just meant to throw you off.

jim has at least ten $ in change, because he spent his paper money.
