Answer:
[tex]\large \boxed{3.00 \, \%}[/tex]
Step-by-step explanation:
The formula for calculating percentage is
[tex]\text{Percentage} = \dfrac{\text{Part}}{\text{Whole}} \times 100 \, \%[/tex]
The "part" is the $240.
The "whole" is the $8000.
[tex]\text{ \% of earnings} = \dfrac{240}{8000} \times 100 \, \% = \mathbf{3.00 \, \%}[/tex]
[tex]\text{\$240 is }\large \boxed{\mathbf{3.00 \, \%}} \text{ of \$8000}[/tex]
