Answer:
8.5 %
Explanation:
The formula used her :
\text{Percent error }=\dfrac{|\text{Estimated value-Actual value}|}{\text{Actual value}}\times100Percent error =
Actual value
∣Estimated value-Actual value∣
×100
Given : A hospital bill is estimated to be $480.00 it ends up actually costing the patient $524.50 .
Then, the percent of Error in the bill will be :
\begin{gathered}\text{Percent error }=\dfrac{\text{524.50}}\times100\\\\=\dfrac-44.5{524.50}\times100\\\\=\dfrac{44.5}{524.50}\times100\\\\=8.48427073403\approx8.5\%\end{gathered}
Percent error =
524.50
∣480−524.50∣
×100
=
524.50
∣−44.5∣
×100
=
524.50
44.5
×100
=8.48427073403≈8.5%
[Rounded to the nearest tenth]
Hence, the percent of Error in the bill = 8.5%
