3 Safin designed and launched an app. One week after he launched the app, it had 8 400 users. Four weeks after he launched the app, it had 23 050 users. The user growth followed the model of an exponential function of the form f(x) = acx, where x: the time elapsed since the app was launched, in weeks f(x): the number of users A company tried to buy Safin's app when it reached 50 000 users. Hoping to make more money, Safin waited and finally sold the app when it reached 400 000 users. To the nearest tenth, how many weeks after the original offer did Safin sell his app?
