Revenue and profit functions. A company manufactures 10- and 3-speed bicycles. The weekly demand and cost functions are p = 230 − 9 x + y q = 130 + x − 4 y C ( x , y ) = 200 + 80 x + 30 y where $ p is the price of a 10-speed bicycle. $ q is the price of a 3-speed bicycle, x is the weekly demand for 10-speed bicycles, y is the weekly demand for 3-speed bicycles, and C ( x , y ) is the cost function. Find R x ( 10, 5) and P x (10, 5), and interpret the results.

Solution Summary: The author calculates the value of R_x(10,5)=60, which means the company revenue will increase 60 when the weekly demand for 10-speed bicycles x increases-
