You are conducting an experiment and there are three acid solutions: 30%, 40%, and 80% acid. It can mix all three to come up with a 100 – gallons of a 39% acid solution. If you interchange the amount of 30% solution with the amount of the 80% solution in the first mix, it can create a 100 – gallon solution that is 59% acid. How many of the 30%, 40%, and 80% solutions are needed to create a 100- gallons of a 39% acid solution? Use two different methods to solve this problem.

Question
Transcribed Image Text:4. You are conducting an experiment and there are three acid solutions: 30%, 40%, and 80%
acid. It can mix all three to come up with a 100 – gallons of a 39% acid solution. If you
interchange the amount of 30% solution with the amount of the 80% solution in the first
mix, it can create a 100 – gallon solution that is 59% acid. How many of the 30%, 40%, and
80% solutions are needed to create a 100 – gallons of a 39% acid solution? Use two different
methods to solve this problem.
