Problema Solution
A chemist has 30% and 50% solutions of acid available. How many liters of each solution should be mixed to obtain 68 liters of 35% acid solution?
Answer provided by our tutors
let
x = liters of the 30% solution
y = liters of the 50% solution
the chemist needs to make a 68 liters mix of 35% acid solution
x + y = 68
0.30x + 0.50y = 0.35*68
by solving the system of equations we find
x = 51 liters
y = 17 liters
