How Much Should A Teenager Weigh?

I am a girl, and someone once told me that you should weigh about 100 lbs at 5ft, and gain somewhere around five pounds for every inch after that (for example, i am 5"6, so my ideal weight would be 130lbs) but evryone is different so there's no exact number for each person.
Personally, i am not so sure about this scale, because the numbers seem fairly high (i am in fact 105 lbs, and play multiple sports, so i have muscle and do not have any eating disorders). If it's really important that you know, I'm sure a doctor would be able to tell you.

It mostly depends of the teens built so there is really a particular weight
