CheapBuys, a large bulk store, sells cases of bottled water for $13.49
. There are 48
bottles in each case and the bottles are
12 ounces each. Sarah remembers that the vending machine at work sells the same size bottle for $0.75
per bottle. Calculate the cost for one bottle and tell if Sarah should buy bottled water by the case or not.

Buying in bulk will not save her any money since the bottles in the case and the bottles from the vending machine are both about 75
cents each.

The cost per bottle at CheapBuys is approximately 28
cents, so Sarah will save a considerable amount of money by buying water in bulk rather than from the vending machine.

The case of water is $13.49
. Since the individual bottles are cheaper in the vending machine, Sarah should buy the bottles at work.

Each bottle of water in the case from CheapBuys is 35
cents, so she should buy the case instead of buying it at work.
