Answer: The grocery store has the better buy because the price per bottle is cheaper.
Step-by-step explanation:
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 a more reasonable buy because it is $1.15 per bottle where as at the convenience store is $1.18 per bottle. So at the grocery store you save ¢3 per bottle.
