Josh wanted to buy a bike but didn't have enough money. Sam slick said "I can fix that. Each time you jump that fence, I'll double your money. There's one small thing though. Each time I pay you, you must give me $56 back for the privilege of jumping." Josh agreed, jumped the fence, received his payment from Sam slick, and paid Sam $56. Repeating the routine 2 more times, josh was distressed to find that, on the last jump after Sam had made his payment to josh, josh had only $56 with which to pay Sam and so had nothing left. Sam of course , went merrily on his way leaving josh wishing that he had known a little more about mathematics.

(A) josh had $ ____ before he made his deal with Sam.

(B) if josh jumps the fence 4 times before running out of money, then he has $_____ before he made his deal with Sam
