You should get:$$1-\frac{12}{16.5}*100=\% \space decrease $$

U can work this question backwards by process of elimination...it has to be less than 50% since half of 16.50 is 8 something! so, lets try option C, 16.50 x (27%) = 4.45
then, 16.5 - 4.45 = 12! 
So, the correct answer is C!
Enjoy!

I guess I forgot the parentheses in there...that should have been:
        a few moments ago
$$(1-\frac{12}{16.5})*100=\% \space decrease$$

@Shane_B! Your method is more formal! That works too!

Either way works...on a test sometimes trying the answers is just the fastest...sometimes not :)
