Answer:
2.5 gallons of the 20% solution must be replaced by the 36% solution.
Step-by-step explanation:
![.12(20 - x) + .36x = 20(.15)](https://tex.z-dn.net/?f=.12%2820%20-%20x%29%20%2B%20.36x%20%3D%2020%28.15%29)
![2.4 - .12x + .36x = 3](https://tex.z-dn.net/?f=2.4%20-%20.12x%20%2B%20.36x%20%3D%203)
![2.4 - .24x = 3](https://tex.z-dn.net/?f=2.4%20-%20.24x%20%3D%203)
![- .24x = - .6](https://tex.z-dn.net/?f=%20-%20.24x%20%3D%20%20-%20.6)
![.24x = .6](https://tex.z-dn.net/?f=.24x%20%3D%20.6)
![x = 2.5](https://tex.z-dn.net/?f=x%20%3D%202.5)
