Question

there is 30 gallons of water and 12 gallons of lysol in a cleaning mixture. what is the percent of the mixture is lysol?

Answer 1

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
