Q = 1.84

Step-by-step explanation:

If we poured 0,5 gallon of mixture A with 0.5 gallon of mixture B we will get a gallon of:

(15 + 50) / 2 = 32.5 %

Now by ule of three

If with 0, 5 gl of A we get 32.5 %

? x 30

x = (0.5) * (0.3) / 0.325

x = 0,462 gl t get a mixture of 30%

Then for 4 gl

Q = 4 * 0.462

Q = 1.84
