Charlene's annual bonus is calculated in the following manner: Charlene receives 20 percent of her first $11,000 in sales and 30 percent of her sales in excess of $11,000. If Charlene received a bonus of $8,500, what were her annual sales? Choose the correct choice from the following answers
A) $ 20,000 B) $ 22,000 C) $ 24,666 D) $ 26,000 E) $ 28,000
Let x be the total sales in $.   For the 1st 11,000 you get 20% ---&gt; 0.2*11000 = 2200$   For the remaining (x-11000) $, you get 30% ---&gt; 0.3*(x-11000)   Thus, 0.3*(x-11000) + 2200 = 8500 ----&gt; x= 24,666 $   $ 24,666 is thus the correct answer.
