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.
[tex]\%error=\frac{Error}{Estimated}\times 100[/tex]
[tex]\%error=\frac{26}{120}\times 100[/tex]
[tex]\%error\approx 21.67[/tex]
Therefore, the percent error is 21.67%.
