Question 325214:  We have a 6% gallon jug of bleach and we want to make a 1% solution of bleach, how much water is needed to make this 1% batch? 1 gal. will make a 3% solution of bleach and we now have 2 gals so then if we added 2 more gals we would have a 1.5% solution with 4 gals, 3 of which were pure water added. Just looking for a good formula to get the right answer, came up with this but not sure if I am correct .06(1Gal) + 0(x)= .01(1+x) so .06 + 0= .01+.01x

-------------------- 
That equation looks good. 
What you have is  
bleach + bleach = bleach 
0.06*1 + 0*x = 0.01(1+x) 
Multiply thru by 100 to get: 
6 + 0 = 1+x 
x = 5 gallon (amt of water you need to add to get a 1% solution)
