Problema Solution
A chemist has one solution that is 30% pure salt and another is 60% pure salt. How many ounces of each solution must he use to produce 60 ounces of a solution that is 50% pure salt?
Answer provided by our tutors
let
x = ounces of 30% pure salt
y = ounces of 60% pure salt
x + y = 60
0.30x + 0.60y = 0.50*60
by solving the above system of equations we find:
x = 20 oz
y = 40 oz

the chemist must use 20 ounces of the 30% pure salt and 40 ounces of the 60% pure salt.
