Error on the 5lb Book of GRE chapter 12 problem 17

[oalandgrave1]

I was searching on the blog but I didnt find any place where the people put issues or errors on the book 5lb Book of GRE. On the problem 17 its not matching the 60% with the 160% of the answers page. They say that need to multiple 1.6 for get the 60% but that is wrong. I you want to find the 60% you need to mulitply by .60. Does anyone find the same issue that I found ?? thanks

It is indeed under student center. It's called "Errata." You'll find mistakes in our books there.

However, it's likely you're thinking about it wrong (I don't have the question in front of me, but feel free to paste it here). Is it asking for an INCREASE of 60%? Because if so, you do need to multiply it by 1.6.
