There are 4 stores. Each store capers $1 to enter and $1 to exit. A man enters one store and spends half of his money. After leaving he proceeds to do the same in the other three stores. How much money did he start shopping with?
You don’t really know. Since he have paid $8 leaving and entering the store and spends half of his money every time. You never told us how much money he have left.
