I'm using the Corporate Finance 11e book by Ross, Westerfield, Jaffe, and Jordan. However, the homework solutions given on this website do not correspond to the numbers in our book. Since the editions are the same, this does not make sense, and it's more difficult to determine where many of the calculations on this site come from, since I can't tell what the original information for each website solution is for each question. Can you please advise, since our book problems/questions for Chapter 2 are numbered 1-22 in the normal way, but, the Chegg website has solutions for problems numbered like, "1CQ, 1CTQ, 1MCQ, 1QP".

Any clarification would be appreciated. Thanks.

Nancy
