A chemist mixed 30% acid and 50% acid solutions and produced 5 gallons of 40% solution. How many liters of each were combined to produce the solutions?

Sagot :

.30x + .50x = 5(.4)
[tex]\frac{4}{5} x =2[/tex]
x = 2.5 gallons

1 gallon is approximately 3.78541
so the chemist used approximately 9.46 L
