0.35x + 0.60y = 0.40(x + y) where x = vol. of 35% and y = vol. of 60%
x + y = 20
solve this system of equations
x + y = 20
-0.05x +0.20y = 0
this gives x = 16 and y = 4
so you need 16 L of 35% and 4 L of 60% solution.
Answer:

Step-by-step explanation:
8.00 +(0.06x) = 18.27
0.08x = 18.27 - 6.00
0.08x = 12.56
12.56/0.08=
