Diet cola was on sale last week; it cost $10 for every 4 liters of diet cola. At this rate, how many liters can you buy with $15?

6 liters of diet cola.

Step-by-step 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!!
