Respuesta :

Total number of the adults are 693

Percentage of adults that show that they erase all of their personal information online is 58%

Geberal expression for the percentage is

[tex]Percentage=\frac{\text{value to whose percentage to be found}}{\text{Total value}}\times100[/tex]

We need to find the number of adults that erase all of their personal information online.

[tex]Percantage=\frac{Number\text{ of the adults who erase thier personal informatio}}{\text{Total number of adults}}\times100[/tex]

Substitute the value

Let x=Number of adults who erase thier personal information

[tex]58=\frac{x}{693}\times100[/tex]

Simplify and solve for, x

[tex]\begin{gathered} 58\times693=100x \\ \frac{40194}{100}=x \\ x=401.94 \end{gathered}[/tex]

Round of the x value

[tex]x=402[/tex]

Number of adults who erase thier personal information are 402.
