There were three cockfit arena that you want to enter. You will enter the first cockfit arena and you need to pay $10.00 as entrance fee, when you arrive at the arena your money will be doubled, when you go out you need to pay $10.00. When you enter the second arena, you need to pay $10.00 again as entrance fee, then inside it your money will become double, when you leave you need to pay $10.00 again.The third is the same you need to pay $10.00 as entrance fee, when inside your money will be doubled and when you out you will pay your last money ( $10.00 ) this time you dont have money left. How much dollar you need to bring?
I think the previous answers are all wrong...
The wording specifically states that your money is doubled INSIDE arena 2 & 3, but it says your money is doubled when you ARRIVE AT arena 1... meaning your money would be doubled before you enter or pay the entrance fee...
You would only need $21.25 when you arrived at #1.....
then doubled upon your arrival to $$42.50, less $10 to enter, less $10 to exit = $22.50
at #2, less $10 to enter = $12.50, doubled INSIDE to $25, less $10 to exit = $15
at #3, less $10 to enter = $5, doubled Inside to $10, less $10 to exit = $0...
The answer, therefore, is $21.25

By working backwards it goes like this:
You end with 0 after paying $10 out the last door. 10/2 = $5 (for it to double) + $10 (the entrance fee to #3)= $15
$15 + $10 (the amount you paid to leave # 2) = $25/2 (for it to double) = $12.5 + $10 (entrance fee to #2) = $22.5
$22.5 + $10 (amount you paid to leave # 1) = $32.5/2 (for it to double) = 16.25 + $10 (entrance fee to #1) = $26.25

If I bring $20, I pay $10 at the first arena which leaves me $10. When inside it is doubled to $20. Then I pay $10 to get out. I have $10 left.
The same happens at each arena. Finally I have $10 left over.
The experience cost me $10 in all.
