A portion of cooked food contains 160 bacteria at the start of storage. The food is stored at a warm, constant temperature.
The table shows the estimated number of bacteria in the food.
| Storage time / minutes | Number of bacteria |
|---|---|
| 0 | 160 |
| 80 | 2560 |
The mean division time remains constant during storage.
Calculate the predicted number of bacteria in the food after a total storage time of 4 hours 20 minutes.
