The number of cellphone subscribers in a certain country in the years 200072005 was projected to follow the equation N(t) = 391' + 73 million subscribers in year t (t = 0 represents January 2000). The average annual revenue per cell phone user was $350 in 2000. If we assume that due to competition the revenue per cell phone user decreases continuously at an annual rate of 20%, we can model the annual revenue as R(t) = 350(39r + 73)e'0-2t million dollars. (a) Determine when to the nearest 0.1 year the revenue was projected to peak. (Submit your answer in terms of 13.) SW (b) Determine the revenue, to the nearest $1 million, at that time
