scott bought two items at daves fruit market. the cashier told him that he owed $5.49. why is the cashier incorrect? what did scott purchase?
DAVE'S FRUIT MARKET
grapes $2.25/bag
bananas $ 1.99/bag
strwberries $3.40/box
watermelon $5.00

The sum of any two items does not add up to $5.49.
Since the last digit in the total is 9, he must have purchased bananas and one of the last two.
