Answer:
6 liters of diet cola.
Explanation:
In order to find the answer to this question you have to find the price per liter of diet cola.
To do this you will have to take $10 and divide it by 4.
10/4 = 2.5
Each liter costs $2.50.
Next, to get the number of liters you can buy, you will take $15 and divide it by $2.50.
15/2.50 = 6
Therefore, the number of liters of diet cola you can buy for $15 is 6.
I hope this helps!!
