Question 1024723

A chemist needs 3L of 60% salt solution. She has a 25% salt solution and 75% salt solution available with her. How many liters of each solution should she mix to obtain her desired solution?
<pre>Let amount of 25% salt solution needed, be T
Then amount of 75% solution needed = 3 - T
Equation formed: {{{.25T + .75(3 - T) = .6T}}}
Solve for T, the amount of 25% solution to be mixed
Subtract T from 3 to get amount of 75% solution to be mixed
