Answer:
40%
Step-by-step explanation:
To find the percentage, set up a proportion!
12/30 = x/100
Now cross multiply!
30 · x = 30x
12 · 100 = 1,200
You are left with:
30x = 1,200
Divide both sides by 30...
And you get....
x = 40
The mixture is 40% lysol!
I hope this clears up any confusion you may have had :D
