The revenue (in thousands of dollars) from producing x units of an item is modeled by R(x) = 13x - 0.001x a. Find the average rate of change in revenue as x changes from 1003 to 1007. b. Find the marginal revenue at x = 11,000. a. The average rate of change in revenue is dollars per unit. (Do not round until the final answer. Then round to the nearest dollar as needed.) K The figure to the right shows the number of full-time employees of a company (in millions) as a function of the revenue generated by the company (in billions). Find and interpret the average rate of change of employees with respect to revenue for the following changes in revenue. 108 64 (a) $4 billion to $32 billion 40 b) $32 billion to $108 billion (c) $4 billion to $108 billion (32 32) 20 10 4 40) 0 20 40 60 80 100 120 Revenue (billions) (a) The average rate of change of employees with respect to revenue for the changes from $4 billion to $32 billion is about employees/billion dollars.
