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.

Would you rather work seven days at $20 per day or be paid $2 for the first day and have your salary double every day for a week?

More problems to try

Question 1

Tom Terrific has a garden in the shape of a rectangle. He wanted to plant a tree in a specific spot. He wanted it to be in the exact center of the garden. What would be a way that he could find the center without using any measurement?
Try using a picture in your answer!!


Question 2


Groups of campers were going to an island. On the first day 10 went over and 2 came back. On the second day, 12 went over and 3 came back. If this pattern continues, how many would be on the island at the end of a week? How many would be left?

Question 3

12:34

You have a digital clock that shows only hours and minutes. How mahy different readings between 11:00 AM and 5:00 PM (of the same day) contain at least two 2s in the time?


The answer is not the most important part of this question. It is the explanation of the journey and how you got to your answer that is.
