20% of the ointment is too weak and 60% is way too strong, but 25% is just right. To get 25% you have to mix 24 fluid onces in volume. How many fluid onces of each did we use? I give out medals :)

    solve using elimination multiply bottom equation by -5 A + B = 24 -A -3B = -30 ------------- -2B = -6 B = 3 A + 3 = 24 A = 21
