Answer:

9672

Step-by-step explanation:

Population growth can be represented by the equation [tex]A=A_0(1+r)^{t}[/tex].

  • [tex]A_{0}[/tex] is the starting population. Here that is 57.
  • r is the rat as a decimal. The rate is 0.31. To convert to a percentage, we multiply by 100. 0.31x100=31%
  • t is the number of hours.
