Oh thank Heaven for 7-11

Here is a tougher problem for you Tyler!!! Good luck people.



A guy walks into a 7-11 store and selects four items to buy. The clerk at the counter informs the gentleman that the total cost of the four items is $7.11. He was completely surprised that the cost was the same as the name of the store. The clerk informed the man that he simply multiplied the cost of each item and arrived at the total. The customer calmly informed the clerk that the items should be added and not multiplied. The clerk carefully added the items together and informed the customer that the total was still exactly $7.11. (There was no sales tax involved) Your task is to determine the exact costs of each item?

Good Luck.

Do the words "Guess and Check" Ring a bell. There is no logical formula for it. So you could be there for hours. There are four variables. You have to guess right. Good luck! You have to have no life to find the answer!
