Question 196272: A solution containing 30% insecticide is to be mixed with a solution of 50% insecticide to make a 200L solution containing 42% insecticide. How much of solutoin is used

Let x represent the amount of 30% solution, then 200- x is the amount of 50% solution.
So .3x is the amount of pure insecticide in the 30% solution, .5(200- x) is the amount pure insecticide in the 50% solution, and .42(200) is the amount of pure insecticide in the mixture, so:
 = .42(200))
Solve for x
