12. A certain alloy contains 5.25% copper. How much copper is there in a piece weighing 200 pounds?
A. 1.05 Pounds.
B. 105 Pounds.
C. 10.5 Pounds.
D. 1050 Pounds.
A--Is not correct.
But we think it is C-- may be correct.
Again, This is NOT my work. I am helping a friend with her English work. Also she does not have the internet. She is from Germany and she’s having a hard time understanding English. With your comments it is helping her to understand English, and also how to use it later. Plus I don’t want to get the wrong answer in showing her. That’s why I am asking for some extra help. Is that a crime?
