Question 864999
Maximum profit. A chain store manager has been told by the main office that daily profit, P, is related to the number of clerks working that day, x, according to the function P = −25x^2 + 300x. What number of clerks will maximize the profit, and what is the maximum possible profit? 
---------------------
Since P is a parabola opening downward from (-b/(2a),f(-b/(2a)))
# of clerks at the max is -b/(2a) = -300/(2(-25)) = 300/50 = 6
----
Max Profit = P(6) = -25(36)+300(6) = -900+1800 = $900
