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 $8,900, what were her annual sales?
Choose the correct choice from the following choices:
A) $ 20,000
B) $ 22,000
C) $ 24,000
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 = 8900 ----&gt; x= 26,000 $   $ 26,000 is thus the correct answer.
