Don't understand answer to problem 68 on page 70 of the OG 2015 quant review. Please help!

hi—welcome to the forum... but a whole bunch of stuff is wrong with this post.

• we can't host OG problems here. (please read the rules—first thread in the folder—before posting. thank you.)

• even if your post is from an allowed source, you can't just say 'i don't understand this problem'.
in that case, we can't really add any value here. our response is going to be (a) 'check out the answer key', or else (b) 'i can't help because i don't know what the problem is'.
in other words, we need specifics.
what do you already understand?
what don't you understand?
what have you tried already?
etc.

thanks.
