3.2 ounces of chemical solution
Assuming you are talking about US fluid ounces, there are 128 fluid ounces in one gallon, and 40% of this is 51.2 ounces.
Let x = ounces of 50% solution, and y = ounces of 1% solution. So that we have: 0.5x + 0.01y = 8(0.2) which is a linear equation in two variables, meaning there are infinitely many choices of mixing those solutions.

That all depends on what you want the final concentration of alcohol to be.
Let a be the number of ounces of 25% alcohol required. Then, 25a + (30x9) = 28(9 + a) 25a + 270 = 252 + 28a 3a = 18 a = 6 Then 6 ounces of 25% alcohol + 9 ounces of 30% alcohol produces 15 ounces of 28% alcohol.
That is 1,536 ounces.
