Question

A grocery store sells a case of 24-500ml bottles of water for $2.99. They also Sell a case of 6-1.5 L bottles for $2.99. Which bottles are the best by? How much are you saving per liter?

Answer 1

24 - 500ml bottles; $.08 per L

Explanation:

1 liter = 1,000 ml

so 500ml = .5 L

Now compare the amount of water: 24 at .5L = 12L

6 at 1.5L = 9L

So the 12L /24 = .5 L per bottle cost about $.25

1.5L/ 6 = .25 L per bottle cost about $.33
