Question

Each week, mr. jones goes to the grocery store. mr.jones estimates that he will spend $120 when he goes to the grocery store this week. He actually spends $94. Find the percent error.

Answer 1

Answer: 28%

Explanation:

Percent Error =
`((given - actual))/(actual) (100)`

1.
`((120-94))/(94) (100)`

2.
`(26)/(94)(100)`

3. (0.28)(100)

Percent Error = 28%

Answer 2

Estimated amount that Mr. Jones thought would be spending each week for grocery = $120
Amount actually spent by Mr.Jones in the grocery store = $94
Error in calculation of the amount of spending = (120 - 94) dollars
= $26
Percentage error in calculation = (26/120) * 100
= (13/6) * 10
= 130/6
= 21.666 percent
= 21.67 percent
So there is 21.67% error in the calculation of Mr. Jones. I hope you got the answer you were looking for.
