Charlene's annual bonus is calculated in the following manner: Charlene receives 20 percent of her first $11,000 in sales and 40 percent of her sales in excess of $11,000. If Charlene received a bonus of $7,300, what were her annual sales? Choose the correct choice from the following answers:
A) $ 10,000
B) $ 12,750
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 40% ---&gt; 0.4*(x-11000)   Thus, 0.4*(x-11000) + 2200 = 7300 ----&gt; x= 12,750 $   $ 12,750 is thus the correct answer.
