Question

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

Answer 1

• Error (e) = 12 - 9 = $ 3

• assumed value (a) = $ 9

`\boxed{ \mathrm{ \% \: error = (error)/(assumed \: value) * 100}}`

• 
  `\mathrm{ \% \: error =(3)/(9) ×100}`

• 
  `\mathrm{ \% \: error = (1)/(3) ×100}`

• 
  `\mathrm{ \% \: error = 33.33 \%}`
