Problema Solution
Maria needs to mix a 10% saline solution with a 40% saline solution to create 200 millileters of a 26.5% solution. How many millileters of each solution must Maria use?
Answer provided by our tutors
Let
x = ml of 10% saline solution
y = ml of 40% saline solution
x + y = 200
0.10x + 0.40y = 0.265*200
........

........
x = 90 ml
y = 110 ml
Maria must use 90 milliliters of 10% solution and 110 milliliters of 40% solution.
