Question 1069565
Use a system of equations to solve this problem.

A chemist currently has two solutions of sodium chloride. One solution has a 5% concentration and the other has a 25% concentration. The chemist needs to make 10 L of a 10% sodium chloride solution.

Let x = the amount of 5% solution.

Let y = the amount of 25% solution.

 

How much of each solution does the chemist need to make?

Enter your answers, as decimals, in the boxes.
<pre>The system of equations you need is: {{{matrix(2,8, x, "+", y, "=", 10, "-------", eq, "(i)", .05x, "+", .25y, "=", ".1(10)", "-------", eq, "(ii)")}}}
Solve to get "x", or the amount of 5% solution to be mixed
Solve to get "y," or the amount of 25% solution.
**Note that the amount of the 5% solution will be 5 times the amount of the 25% solution.
