PROBLEM # 2
 A solution that is 10% anti-freeze is mixed w/ a 20% anti-freeze
to produce 50L of solution that is 15.6% anti-freeze. How many litres
of the 10% solution are used?
 The total amount of solutions is 50 L
SOLUTION #2
 The anti-freeze in the mixture comes from the anti-freeze in each
solution. 
SOLUTION #2.1
Strength of
solution
Litres of
solution
= Litres of
Anti-Freeze
10% Solution
0.10
s
= 0.10s
20% Solution
0.20
(50-s)
= 10 – 0.20s
15.6% Mixture
0.156
50
= 7.8
SOLUTION # 2.2
 0.10 s + (10 – 0.20s) = 7.8


-0.10s + 10 = 7.8
-0.10s = -2.2
-0.10 -0.10

s = 22 L

50-s = 28 L
