Question

You are making a saline solution in a science
class. One hundred milliliters of a 45.84%
saline solution is obtained by mixing a 34%
saline solution with a 71% saline solution.
a) How much 71% saline solution must you
use?
Answer in units of milliliters

Answer 1

First change percents to decimals.
Let
x = # milliliters of 34% saline solution
y = # milliliters of 71% saline solution

This gives us a system of equations

x + y = 100
.34 x + .71y = 100 * (.4584)
