You can put this solution on YOUR website! ------------------------ percent ---------------- quantity
30% alcohol 30 ---------------- 5 gallons
Water 0 ----------------x gallons
Mixture 25 ----------------5+x gallons
30*5+0x =25(5+x)
150+0 x=125+25x
0x-25x= 125-150
-25x =-25
/ -25
x=1 gallon of Water
