Question

Molly estimated the her car insurance was going to be $250 each month. It was actually going to be $230 each month. What is the percent error? *

Answer 1

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 :

$\%=\dfrac{|\text{estimated-actual}|}{\text{actual}}\times 100\\\\=\dfrac{250-230}{230}\times 100\\\\=8.69\%$

So, the percent error is 8.69%.
