Question

It is the policy of stores owned by the Talkara Co. to give out bonuses to salespeople every six months. The size of the bonus is determined by averaging (taking the mean of) the two highest and the lowest monthly sales totals from the six-month period, taking 8% 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. July, 27.7; August, 25.6; September, 19.7; October, 25.3; November, 23.6; December, 22.2.

Answer 1

First pick the two highest and the lowest sales: 27.7, 25.6, and 19.7 (thousands).
Their average = (27.7 + 25.6 + 19.7) / 3 = 73.0 / 3 = 24.333... (thousand).
8% of that = 0.08 × 24.333... = 1.946666... (thousand) = $1,946.67.
Split among six people: 1.946666... / 6 = 0.324444... (thousand) = $324.44 ≈ $324.

Answer: C.
