A scientist investigates a species of bacterium that can break down waste. The bacteria are placed in a small chamber containing enough nutrients and kept at a suitable temperature.
| Time in minutes | Number of bacteria |
|---|---|
| 0 | 120 |
| 90 | 960 |
Calculate the predicted number of bacteria in the chamber 4 hours after the start of the investigation.
Assume that the mean division time remains constant.
