Answer:
B
Explanation:
You just divide the price by how many water bottles they have listed and the store with the smallest price per bottle is the right answer.
Store 1
10.49/12 = 0.87 cents per bottle
Store 2
3.89/12 = 0.32 cents per bottle
Store 3
7.99/6 = 1.33 dollars per bottle
Store 4
2.29/6 = 0.38 cents per bottle
Stoer 2 is cheapest
