Answer:
[tex]\boxed{8900; 61 \, \%}[/tex]
Explanation:
The total estimated population (P) is
[tex]P = \text{115 ha} \times \dfrac{\text{ 77 beetles}}{\text{1 ha}} = \textbf{8900 beetles}\\\\\begin{array}{rcl}\text{ \% K} & = & \dfrac{\text{Population}}{K} \times 100 \, \% \\\\& = & \dfrac{8900}{14 600} \times 100 \, \% \\\\ & = & \mathbf{61 \, \%}\\\end{array}\\\text{The population is now at }\boxed{\mathbf{61 \, \%}} \text{ of carrying capacity}[/tex]
