Grocery store:

price per bottle = 13.80/12 = $1.15 per bottle

Convenience store:

price per botttle = 11.80/10 = $1.18 per bottle

The grocery store is cheaper, as the cost per bottle is lower.

To find out the price per bottle, divide the total cost by the number of water bottles. 

Grocery Store: Price per bottle=$13.80÷12
                                                 =$1.15 

Convenience Store: Price per bottle=$11.80÷10
                                                         =$1.18

The grocery store has the better buy because the price per bottle is cheaper.
