"if u get this question wrong u have to change your profile picture to psyduck for 3 days and if u know the answer don't tell anyone but me((pm me)) *because the answer is a secret.* if u bring 10 empty bottles to the bottle shop, the bottle shop will change 10 empty bottles to 1 drink. if u bring 100 bottles to the shop. how many drinks will you get? " do u know the answer? ?

The answer is 10 drinks. This is the example of a simple proportion. 10 bottles will be changed for 1 drink. 100 bottles will be changed for x drinks. Make the proportion. 10 bottles : 1 drink = 100 bottles : x. Rearrange it. 10 bottles * x = 100 bottles * 1 drink. Express it for x. x = 100 bottles * 1 drink : 10 bottles. x = 10 drinks. So, for 100 bottles you will get 10 drinks.
