<span>In order to calculate this, we can set up a simple ratio. We say that
10 empty bottles : 1 drink
100 empty bottles : x drinks
We cross multiply to form the equation:
10x = 100
Now, we can simply solve for x to determine the number of drinks we would get for 100 bottles.
x = 10
So we will get 10 drinks if we bring 100 bottles to the bottle shop.Hope this helps. Let me know if you need additional help!</span>
