Question 354396: An auto mechanics has two bottles of battery acid solutions. One contains 10% acid and the other 4% acid. How many cubic centimeters of each solution must be used to make 120 cm³. Answer by Alan3354(69443) (Show Source):
You can put this solution on YOUR website! It depends on what concentration you want.
Here's a similar problem.
--------------
an alloy of metals is 25% copper. Another alloy is 50% copper. How much of each alloy should be used to make 1000 grams of an alloy that is 45% copper?
---------------------
t = amount of 25%
f = amount of 50%
--------
t + f = 1000
0.25t + 0.5f = 0.45*1000
Can you finish it?
