Answer:
2.5 gallons that are removed and 2.5 gallons of bleach that are added
Explanation:
Let's take as
x = amount of the original solution that is removed and the amount of bleach to add.
The equation for the amount of lye is equal to:
0.04*(60 - x) + x = 0.08*(60)
2.4 - 0.04x + x = 4.8
-0.04x + x = 4.8 - 2.4
0.96x = 2.4
Clearing x:
x = 2.4/0.96
x = 2.5 gallons that are removed and 2.5 gallons of bleach that are added
