Answer:
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)
The answer to your question is,
$3.84, you take $69.20 and divide it by 18 and there is your answer!
