Problema Solution
Melanie needs to mix a 10% saline solution with a 50% saline solution to create 100 millileters of a 26% solution. How many millileters of each solution must Melanie use?
Answer provided by our tutors
let
x = milliliters of the 10% solution
y = milliliters of the 50% solution
Melanie needs to mix a 10% saline solution with a 50% saline solution to create 100 milliliters of a 26% solution
x + y = 100
0.10x + 0.50y = 0.26*100
by solving the system of equations we find
x = 60 ml
y = 40 ml
