Question

Answer 1

Mr. Jones estimate is wrong then.  It is $26 more than he actually bought.

Answer 2

Error = 26, Percent error = 21.67%.

Explanation:

It is given that mr.jones estimates that he will spend $120 when he goes to the grocery store this week.

He actually spends $94.

Let as assume we need to find the percent error.

Error = Estimated - Actual

Error = 120 - 94

Error = 26

Formula for % error.

`\%error=(Error)/(Estimated)* 100`

`\%error=(26)/(120)* 100`

`\%error\approx 21.67`

Therefore, the percent error is 21.67%.
