Problema Solution
A 3% saline solution is combined with a 5% solution saline solution to form 10 ounces of a 3.8% saline solution. How many ounces of the 3% solution are used?
Answer provided by our tutors
let
x = ounces of 3% saline solution
y = ounces of 5% saline solution
A 3% saline solution is combined with a 5% solution saline solution to form 10 ounces of a 3.8% saline solution:
x + y = 10
0.03x + 0.05y = 0.038*10
by solving the above system of equations we find:
x = 6 oz
y = 4 oz
