Question

The number of votes for candidate B was estimated to be 905. After the election, the actual number of votes for candidate B was 882. What is the percent error in the estimate? Enter your answer, rounded to the nearest tenth, in the box. %

Answer 1

we can use the formula of percent error

`e=(|r-a|)/(r)*100`

where r is the real value and a the approximate value

then replacing

`e=(|882-905|)/(882)*100`

and solving

`\begin{gathered} e=(|-23|)/(882)*100 \\ \\ e=(23)/(882)*100 \\ \\ e=0.026*100 \\ e=2.6 \end{gathered}`

the percent error is 2.6%
