Problema Solution
How much 2% acid must be mixed with 10% acid to obtain 2000 ml of 8% acid
Answer provided by our tutors
let
x = ml of 2% acid
y = ml of 10% acid
by mixing x and y we obtain 2000 ml of 8% acid thus
x + y = 2000
0.02x + 0.1y = 0.08*2000
by solving the above system of equations we find
x = 500 ml
y = 1500 ml
