a chemist mixed a 15% glucose solution with a 35% glucose solution. This mixture produed 35 liters of 19% glucose solution. How many liters of each solution did the chemist use in the misture?

  • Algebra -

    Let x = the volume of the weak solution
    Let y = the volume of the strong solution

    x + y = 35 (total volume)
    0.15 x + 0.35 y = (0.19)*35 = 6.65
    (amount of glucose in mixture)

    Solve those two simultaneous equations.
