CHILD'S DOSE EQUALS THE AGE OF CHILD DIVIDED BY THE AGE OF CHILD PLUS 12 TIMES ADULT DOSE.

If a 12year old child's dose of a particular medication is 15mg, what is the adult's dose?
-------------------------
CD = CA/(CA+12S)
15mg = 12/(12 + 12AD)
15mg = 1/(1+AD)
15 + 15AD = 1
15AD = -14
AD = -14/15
-----------------
That doesn't make any sense.
Did you post the correct information?
Cheers,
