A certain company gives its salespeople a bonus every six months. This bonus is calculated by averaging (taking the mean of) the four middle monthly sales values (that is, ignoring the highest and lowest) from the six-month window, taking 12% of the result, and splitting it evenly among the salespeople. The graph below shows sales for the most recent bonus period. A bar graph titled Total Sales has month on the x-axis and sales (dollars times 1,000) on the y-axis. January, 21.6; February, 18.9; March, 29.2; April, 18.4; May, 17.1; June, 26.1. If there are five salespeople, how much money will each one receive, to the nearest dollar? a. $556 b. $525 c. $510 d. $486
