Answer:
108 ounces
Step-by-step explanation:
Let x = the number of ounces of Solution A
Let y = the number of ounces of Solution B
Equation 1: x + y = 180
Equation2: y = 180 - x
.60x+.85y=.75(180)
.60x+.85y=135
Multiply both sides of the equation by 100 to remove the decimal points.
60x+85y=3500
60x+85(180 - x)=13500
60x+15300-85x=13500
-25x=-1800
x=72ounces
y=180-72
y=108 ounces
