cast iron contains 4.25% carbon. Find the weight of a bar which contains 1.7 lbs of Carbon

Sep 17th, 2014

If cast iron contains 4.25% carbon, then that means 4.25%, or 0.0425 of the iron bar will be carbon.

If a bar has 1.7 lbs of carbon, 4.25% of the weight of that bar is 1.7 pounds. So, we set up the equation:

0.0425x=1.7, with x being the weight of the bar in pounds (lbs).

Divide both sides by 0.0425, and you get x=40.

So, the bar weighs 40 pounds.


Hope this helped and thanks!
