Question

A grocery store sells twelve water bottles for $13.80. A convenience store sells 10 water bottles for $11.80. Which store has the better or more reasonable buy??

Answer 1

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.

Answer 2

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
