An app creator tracked the sales of his app for the first 14 days after it was released. Since the sales slowed over time, a logarithmic model can be used to model the data.
|Total Number of Sales since Launch||217||552||807||897||1 001||1 080||1 126||1 162||1 218||1 275||1 290||1 335||1 367||1 393|
