Answer:
120 ounces of Solution A; 60 ounces of Solution B
Explanation:
Let the amounts of solution A and solution B be x and y, respectively.
Equation of the amount of solution:
x + y = 180
Equation of the amount of salt:
0.4x + 0.55y = 0.45 × 180
x + y = 180
40x + 55y = 8100
40x + 55y = 8100
-40x - 40y = -7200
-------------------------------
15y = 900
y = 60
x + y = 180
x + 60 = 180
x = 120
Answer:
120 ounces of Solution A; 60 ounces of Solution B
