Answer :

Answer:

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
