Answer:
3 ounces of medication to be added to get 20%solution of medication
Step-by-step explanation:
To find:
The amount of medication to be added to 12 ounces of water to get a 20% solution
Let the amount of medication to be added =x
So total amount of mixture = amount of water + amount of medication
= 12+x
% medication = (amount of medication÷total amount of the mixture)× 100
Therefore
% medication =( x÷12+x)×100
20 =( x÷12+x)×100
X 100
20(12+x) =100x
240+20x =100x
100x-20x =240
80x =240
x =240÷80
x=3
so 3 ounces of medication to be added to get 20%solution of medication
