Question 542945: Hello, I am stuck on a mixture word problem. We have to use 2 unknowns (i.e., Let x=___ & Let y=____) and use the 6 step approach. Here is the question:
A biologist has two brine solutions, one containing 5% salt and another containing 20% salt. How many milliliters of each should she mix to obtain 1L of a solution that contains 14% salt?

� 6 step approach ?

let x = amount of 5% ___ let y = amount of 20% ___ 1000 mL = 1L

x + y = 1L

(5%)(x) + (20%)(y) = (14%)(1)
