The number of cell phone subscribers in a certain country in the early 2000s was projected to follow the equation, N(t) = 40t + 75 million subscribers, in year t (t = 0 represents 2000). The average annual revenue per cell phone user was $350 in 2000. (a) Assuming that, because of competition, the revenue per cell phone user decreases continuously at an annual rate of 10%, give a formula for the annual revenue in year t. R(t) = %3D (Б) Using the model you obtained in part (a) as an estimate of the rate of change of total revenue, estimate the total revenue from 2000 into the indefinite future.
