**Ms. Sue**, Sunday, November 9, 2008 at 7:24pmLet's set up an equation and solve for x (the original price of the boots).

0.3x = 23.97

x = ?

does that happen to all kinds of percentage word problems?

**Ms. Sue**, Sunday, November 9, 2008 at 7:32pmAll percentage word problems can be solved this way -- but you need to be careful about the way you set it up.

For instance, if you wanted to know what he paid for the boots, knowing that he received 30% off of $79.90 --

0.7 * 79.9 = ?

**anjelika**, Sunday, November 9, 2008 at 7:34pmdo you mean 0.7 or 0.3 * 79.9?

**Ms. Sue**, Sunday, November 9, 2008 at 7:36pmWith 30% off, he paid 70% of the original price.

**anjelika**, Sunday, November 9, 2008 at 7:36pm0.3*79.9=23.97

Thank you Ms. Sue :)

**anjelika**, Sunday, November 9, 2008 at 7:47pmoh right! my teacher always reminds me, but I seem to skip it all the time and get -.5 on quizzes for putting it the other way around or forgetting it.

thanks for the reminder Writeacher!
