Question

You estimate 200 people attend concert. Actual was 240. Find percent error. What other estimate gives the same percent error

Answer 1

Answer: 20% and 160

Step-by-step explanation:

Absolute difference = | 240-200 |

= 40

Therefore percentage error

(40/200)*100

20%

With same error percentage

The absolute difference should be 40

= | 160 - 200 |

= |-40|

= 40
