how many ounces of a 26% alcohol solution and a 44% alcohol solution must be combined to obtain 56 ounces of a 29% solution?

Answer 1

If there are x ounces of 26%, then the rest (56-x) is 44%.

So, just calculating the amount of alcohol in each part, and in the total, you have

0.26x + 0.44(56-x) = 0.29*56

Now find x, and 56-x

Answer 2
