Solutions due by high noon on Friday, Feb. 6.
7-ELEVEN A student makes a 7-ELEVEN run and goes to the cash register with four items.
The clerk rings them up and says "The total price is $7.11. Hey, that's funny - the prices of your four items just happen to multiply exactly to $7.11!"
The customer says "Wait a second; you shouldn't multiply the prices... you should add them!"
The clerk realizes this is true, rings the items up properly and says "Hey, that's funny too - the prices of your four items also add up exactly to $7.11!"
What are the prices of the four items? Show your work, which may involve either algebra or a short program.
This problem is brought to you by Prof. Lisa Torrey.
