Math CentralQuandaries & Queries


Question from roger:

I have 100 gallons of 100% glycol. I need to make this a 20% solution, would I just add this to 400 gallons to make the 20% glycol solution?

Hi Roger.

That would work.

100 gallons of glycol + 400 gallons of water is 500 gallons of solution and 100 / (100 + 400) = 20%.
