Each of the six friends Alex, Barry, Chris, Derek, Elmer and Frank visited their friendly neighborhood department store to purchase a particular item and the respective amounts by which they fell short of the price of the item was $ 30, $ 29, $ 28, $ 26, $ 24 and $ 23. Even when the six friends pooled their finances together, they did not have enough money to buy the item.
