The expression 20w represents the amount of water in a number of bottles. What does the variable w represent

Hey there!

If we have 20 times w, or 20w, we can first assume that w means the amount of water bottles, because it starts with a w.

This makes sense because we would have 20 liters of milliliters in each bottle, and you would be multiplying that by the number of bottles which is the independent variable to get the total amount of water, the dependent variable.,
