gabe needs 60 liters of a 40% solution. he currently has a 30% solution and a 60% solution. how many liters of each does he need to make the 60 liters of 40% acid solution

Answer 1

X+y = 60

0.3x+ 0.6y = 60*0.4 = 24

0.3x + 0.6(60 - x) = 24

0.3x + 36 - 0.6x = 24

-0.3x = -12

3x = 120

x = 40

y = 20
