41.67 ounce of pure water should be added to 25 ounces of the 8% salt solution to dilute it to a 3% solution
An equation is an expression that shows the relationship between two or more numbers and variables.
Let x represent the amount of pure water needed to dilute the solution. Hence:
8% * 25 = 3% * (x + 25)
2 = 0.03x + 0.75
x = 41.67 ounce
