Answer:
100 ml of 5% solution
200 ml of 20% solution
Step-by-step explanation:
x = amount of 5% solution
y = amount of 20% solution
System of equations:
x + y = 300
.05x + .20y = 300(.15)
Solve by substitution: let y = 300 - x
.05x + .2(300-x) = 300(.15)
.05x + 60 - .20x = 45
-.15x = -15
x = 100, therefore y = 200
