Posting Guidelines (Summary)

Welcome to our tutoring boards! :) This page summarizes the main points from our posting guidelines. As our name implies, we provide math help (primarily to students with homework). We do not generally post immediate answers or step-by-step solutions. We don't do your homework. We prefer to...

Then do what it says, showing whatever work you have been able to do, so we can see where you are stuck. There are several issues that may cause you trouble, and we need to know which to explain.

In particular, there are some odd things about the question. The word "preferred" seems wrong, and also "another"; and there is no "percentage increase or decrease" to identify, since nothing has changed. I suspect that you (or someone else?) may have copied or translated this inaccurately from its source. Or perhaps this is just part of a larger problem that you failed to show us.
