Answer 1

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

Answer 2

Answer:

Error = 26, Percent error = 21.67%.

Step-by-step 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.

$\%error=\frac{Error}{Estimated}\times 100$

$\%error=\frac{26}{120}\times 100$

$\%error\approx 21.67$

Therefore, the percent error is 21.67%.
