Bottle X contains 10% acid and bottle Y contains 20% acid. In what ratio, of the quantity of bottle X to the quantity of bottle Y, do I need to mix the liquid from the two bottles if I want to create a mixture that is 16% acid?
+36916 Pick an amount to finish with...say 100cc
x = x amount 100-x = y amount
.1x + .2(100-x) = .16 (100)
.1x + 20 - .2x = 16
.1x = -4
x = 40 then y = 60 x:y is then 40:60 = 2:3
