Question 726103
it appears that if you add 100 ml of a 0% solution, then you will have 200 ml of a 3% solution.


6% solution in 100 ml is equal to 6 ml because 6 ml divided by 100 ml = .06 which is equivalent to 6%.


6 ml divided by 200 ml is equal to .03 which is equivalent to 3%.


the formula that can be used is:


x = the amount of 0% solution you need to add.


you get .06 * 100 + 0 * x = .03 * (100 + x)


you are adding 100 ml of 6% solution to x ml of 0% solution to get a total of (100 + x) ml of 3% solution.


the formula becomes:


.06 * 100 + 0 * x = .03 * (100 + x)


simplify to get:


.06 * 100 + 0 * x = .03 * 100 + .03 * x


simplify further to get:


6 = 3 + .03 * x


subtract 3 from both sides of the equation to get:


3 = .03 * x


divide both sides of the equation by .03 to get:


3 /.03 = x


simplify to get:


100 = x.


you need to add 100 ml of 0% solution to 100 ml of 6% solution to get 200 ml of 3% solution.
