Mixture Problem Solution A is 15% acid and solution B is 65% acid. How many liters of solution A and solution B should be mixed together to get a final mixture of 9L with a concentration of 40% acid
a. Solution A 45L and Solution B 4.5L
b. Solution A3L and Solution B 6L
c Solution A 3.75L and Solution B 5.5L
d. Solution A 6L and Solution B 3L

none of the above.

for one of the equations to be used in the process, there has to be a term in the equation since squared is .

since there is only a term in the first equation, we cannot derive a from completing the square.

solving with completing the square

answer: all the values are within because it has a pattern that repeats from -6 to 4.

good luck!
