I'm trying to figure out the calculation for cost of my local bleach however im failing to be able to get the cost per cent of sodium hypo.
The local store by me offers 1 gallon 12.5% for 5$. I see that it is a bit high compared to the locked thread above.
I've tried doing different formulas to reach the cost per cent of sodium hypo but im too far removed from math to figure it out. If someone could leave me the formula so I can check on my own at other stores near me that would be great! Thanks!
