Weighted Averages HELP?

you are performing a science experiment but you don't have the right concentration of sulfuric acid. you have to mix 20% acide with 50% acide to get a mixture that is 30% acid. how much o the 50% acide do you need to mix with 2 liters of 20% acid to get 3 liters of 30% acid?
