Effect of advertising. Suppose that SpryBorg Inc. introduces a new computer game in Houston using television advertisements. Surveys show that P % of the target audience buys the game after x ads are broadcast, satisfying P ( x ) = 100 1 + 49 e − 0.13 x . a. What percentage buys the game without seeing a TV ad ( x = 0 ) ? b. What percentage buys the game after the ad is run 5 times? 10 times? 20 times? 50 times? 60 times? c. Find the rate of change, P ' ( x ) . d. Sketch a graph of the function.
