From the sentence, we get these two relations:
[tex]\begin{gathered} 39\to100\text{percent} \\ 34\to x\text{ percent} \end{gathered}[/tex]Which can be rewritten as:
[tex]\begin{gathered} \frac{100}{39}=\frac{x}{34} \\ \end{gathered}[/tex]Solving for x:
[tex]\Rightarrow x=\frac{34\cdot100}{39}=87.17948\ldots[/tex]Now, rounding the answer:
[tex]\Rightarrow x\approx87percent[/tex]After rounding, the answer is 87%
