Problem 17, Chapter 4 of Guide 3, third edition

[alexambroz]

Don't want to get too involved here as it looks like a simple error in the book. On page 75 the answer reads:

"S2 = 15(3) = 45 and S4 = 135(3) = 405. Therefore S4-S2 = 405-15 = 390."

Seems like it should instead read S4-S2 = 405-45 = 360, no?

Thanks.

Hi Alex,

You are correct. This has been corrected in the fourth edition of our Strategy Guides.
