Write an equation that relates the number of bottles to the total volume of water.

V = 17n

Step-by-step explanation:

Elena has some bottles of water that each hold 17 fluid ounces.

Let n = number of bottles, in fluid ounces.

Let V = volume of water.

V = 17n

This means that for every bottle, there will be 17 more fluid ounces of total volume of water.
