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!
