Answer:
1,500 bacteria.
Explanation:
I don't know what P=Aekt means but I understand the rest:
Hour 0: 1,000 bacteria
Hour 6: 1,300 bacteria
We can conclude from this evidence that it takes 6 hours to grow 300 new bacteria.
Let's use a ratio
new bacteria : hours
300 : 6
50 : 1
500 : 10
So we get 500 new bacteria after 10 hours. Using our original population of 1,000 and our new added members, we get 1,500 bacteria at Hour 10.
