Question

Jordan estimated that his paper airplane would fly 42 feet. It actually traveled 50 feet. What was the percent error?

Answer 1

`\huge \mathcal{ Answer࿐}`

• Error (e) = 50 - 42 = 8 feet

• assumed value (a) = 42 feet

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

• 
  `\mathrm{ \% \: error =(8)/(42)} * 100`

• 
  `\mathrm{ \% \: error = (800)/(42) }`

• 
  `\mathrm{ \% \: error = 19.04 \%}`
