daniellelovee · Answer

ok now 13120/100=x/2

anonymous · Answer

so the 2% of 13120 is 262.4

daniellelovee · Answer

ok if im honest with you this seems more difficult than when I first read it 
 but I would substract 400 minus that value but I think I did this wrong if something you can ask the @mathmate tomorrow

$$\sf \text{400 sheets of steel} \cdot \frac{\text{32.8 kilograms}}{\text{1 sheet}} = 13120~\text{ kilograms of steel}$$$$\sf 13120~~ \text{kilograms of steel} \cdot \frac{2}{100}=\text{262.4 kilograms of steel}$$

I think @daniellelovee 's doubt was what to do next.
In fact, she has correctly helped you to get the quantity (weight) of scrap, which @jhannybean has recalculated for you.  
Since we are told "2% of the steel used became scrap", so the 2% value of 262.4 kg you calculated is the correct answer.
If you have doubts how to get that, review jhannybean's work and post if you have questions.
