51 %
Explanation
to solve this we can use a rule of three
Step 1
set the proportion
[tex]\begin{gathered} x=renevue\text{ Company A compared as a percentate for company B} \\ \end{gathered}[/tex]so,
[tex]\begin{gathered} \text{if } \\ $567$\text{ }\rightarrow\text{ 100\%} \\ 289\rightarrow x \end{gathered}[/tex]the propotion is
[tex]\frac{567}{100}=\frac{289}{x}[/tex]Step 2
solve for x
[tex]\begin{gathered} \frac{567}{100}=\frac{289}{x} \\ \text{cross multiply} \\ 567\cdot x=289\cdot100 \\ 567x=28900 \\ \text{divide both sides by 567} \\ \frac{567x}{567}=\frac{28900}{567} \\ x=50.970 \\ \text{rounded} \\ x=51 \end{gathered}[/tex]therefore, the answer is 51%
