Answer:
x = 15 ounces
Step-by-step explanation:
A mixture is made with two types of solutions.
Solution A - 45 ounces of 10% saline solution
Solution B - x ounces of 70% saline solution
Resulting mixture - (x + 45) ounces of 25% saline solution
To get the value of x, equation will be,
(45 × 0.10) + (x × 0.70) = (x + 45) × 0.25
4.5 + 0.70x = 0.25x + 11.25
0.25x - 0.70x = 4.5 - 11.25
-0.45x = -6.75
x =
x = 15 ounces
