Problema Solution
Gabe Amodeo, a nuclear physicist, needs 60 liters of a 70% acid solution. He currently has a 50 % solution and a 80 % solution. How many liters of each does he need to make the needed 60 liters of 70% acid solution?
Answer provided by our tutors
Let
x = liters of 50% solution
y = liters of 80% solution
x + y = 60
0.50x + 0.80y = 0.70*60

........
x = 20 L
y = 40 L
Gabe Amodeo needs 20 liters of 50% solution and 40 liters of 80% solution.
