in the lab, teresa has two solutions that contain alcohol and is mixing them with each other. she uses 4 times as much
solution a as solution b. solution a is 17% alcohol and solution b is 12% alcohol. how many milliliters of solution b does
she use, if the resulting

mixture has 560 milliliters of pure alcohol?
number of milliliters of solution b:

Step-by-step explanation:

Assume as a basis  the final mixture is 1000 mL.  That means 399 mL of alcohol

Let x = mL of Soln A and y = mL of soln B.

x = 2y.

Now x + y = 1000

and  0.2x + 0.17y = 399

but x = 2y so 0.4y + 0.17y = 399

0.57y = 399.

y = 700 mL  (That is your mL of solution B)

i dont know and i dont care for math bc it is a stupied subject
