Elyset planned to make treats for every student in her class. She thought there were 32 students, but there were actually 30. What was her percent error?

Respuesta :

ANSWER

6.67%

EXPLANATION

We want to find Elyset's percent error.

To find percent error, we have:

[tex]\frac{|Expected\text{ value - Exact value|}}{Exact\text{ value}}\cdot\text{ 100}[/tex]

Therefore, we have that:

[tex]\begin{gathered} \frac{|32\text{ - 30|}}{30}\cdot100 \\ \frac{2}{30}\cdot100 \\ 6.67\text{ \%} \end{gathered}[/tex]

The percent error is 6.67%
