A chemist wishes to make 3 liters of a 7% acid solution by mixing a 9% acid solution and a 4% acid solution. How many liters of each solution should the chemist use? Write your answer as a complete sentence.

First label the unknowns

x = # liters of 9% acid solution
y = # of liters of 4% acid solution

Then use the directions to make equations.

x + y = 3
.09x + .04y = .07 (3)

Answer 7

the first equation deals with total amounts of solutions.
The second equation deals just with the pure acid. Percents are changed to decimal numbers
