A 20% acid solution is mixed with a 70% acid solution to get 50 liters of a 40% solution.
2 answers:
20% solution+70% solution=50% solution
total is 50
so the quantaties are x and 50-x (x+50-x=50)
0.2(50-x)+0.7(x)=0.4(50)
solve
distribute
10-0.2x+0.7x=20
10+0.5x=20
minus 10 both sides
0.5x=10
times 2
x=20
