Timmy estimated he would spend $9 at the candy store. He went a little over-budget and spent $12. What was the percent error?

kap26 [50]

<h2>Answer :</h2>

Error (e) = 12 - 9 = $ 3

assumed value (a) = $ 9

$\boxed{ \mathrm{ \% \: error = \dfrac{error}{assumed \: value} \times 100}}$

$\mathrm{ \% \: error =\dfrac{3}{9} ×100}$

$\mathrm{ \% \: error = \dfrac{1}{3} ×100}$

$\mathrm{ \% \: error = 33.33 \%}$
