Answer:
8.69%.
Step-by-step explanation:
Estimated value = $250
Actual value = $230
We need to find the percent error. It can be calculated as follows :
[tex]\%=\dfrac{|\text{estimated-actual}|}{\text{actual}}\times 100\\\\=\dfrac{250-230}{230}\times 100\\\\=8.69\%[/tex]
So, the percent error is 8.69%.
