Answer:
10,600
Step-by-step explanation:
The bacteria grew in 2 hours by 800. Divide that and that it by 400 per hour.
Since it is a proportional rate, we can assume that the rate continue through till midnight.
Since midnight is 12 hours after noon then the bacteria grow 400 (12)=4800.
We add this to the population at noon 5800+4800=10,600.
