Damn you Math Nazi!
I was close!
s*** were's my math book?

Found it... According this I was right... probally

Setting Up the Percent Equation:
Using the above translations, setting up a correct equation is easy - just remember, the percent must be worked with as a decimal. If you are given a percent in the problem, change it to a decimal for the calculation. If you are finding a percent, your calculation will result in a decimal and you must change it to a percent for your answer.
When setting up the equation, if the n is by itself on one side of the equal sign, simplify the other side of the equation to get your answer. If there is a number being multiplied by the n, divide both sides of the equation by that number.
Example 1:
What is 9% of 65?
n = 0.09 65
n = 5.85
Example 2:
72 is what percent of 900?
72 = n 900
72/900 = n
n = 0.08 = 8%
Chojin said:Hmm,
186.07 * 1.15 = 213.9
194.22 * 1.15 = 223.4
-vs-
(186.07 / .85) = 218.9 = (186.07 - 15%)
(194.22 / .85) = 228.5 = (194.22 - 15%)
