Useful life . An amusement company maintains records for each video game it installs in an arcade. Suppose that C ( t ) and R ( t ) represent the total accumulated costs and revenues (in thousands of dollars), respectively, t years after a particular game has been installed. If C ′ ( t ) = 2 and R ′ ( t ) = 9 e − 0.3 t then find the area between the graphs of C ′ and R ′ over the interval on the t axis from 0 to the useful life of the game and interpret the results.
