(a) To determine To calculate: The number of bird feeders that should be sold to earn the maximum weekly profit by The Outdoor Life Company, when the function to compute the weekly profit is f ( x ) = − 0.4 x 2 + 80 x − 200 , where x represents the number of bird feeders built and sold. Explanation Given Information: The weekly profit earned by selling the bird feeders is given by f ( x ) = − 0.4 x 2 + 80 x − 200 , where x represents the number of bird feeders built and sold. Formula used: The maximum value of a quadratic equation f ( x ) = a x 2 + b x + c where a < 0 occurs at the vertex. The coordinates of the vertex are ( − b 2 a , 4 a c − b 2 4 a ) . Calculation: Consider, the function f ( x ) = − 0.4 x 2 + 80 x − 200 that is function to compute the weekly profit earned by selling bird feeders, where x represents the number of bird feeders built and sold (b) To determine To calculate: The maximum weekly profit received by selling the bird feeders, whose weekly profit is given by the function f ( x ) = − 0.4 x 2 + 80 x − 200 , where x represents the number of bird feeders built and sold.
