An office remodeling job takes 5 &amp; 1/2 days to complete. Before working
Oksana_A [137]

Answer: The percent of the estimated time is the actual time is about 14%.

Step-by-step explanation:

As per given,

Actual time of completing the job = 5\dfrac{1}{2}\text{ days}=\dfrac{11}{2}\text{ days}

Estimated time for completing the job = 4\dfrac{3}{4}\ \text{days}=\dfrac{19}{4}\ \text{days}

The percentage error is given by:-

\%\text{ error}= \dfrac{|\text{Estimated-Actual}|}{\text{Actual}}\times100

=\dfrac{|\dfrac{19}{4}-\dfrac{11}{2}|}{\dfrac{11}{2}}\times100\\\\\\=\dfrac{|\dfrac{19-22}{4}|}{\dfrac{11}{2}}\times100\\\\\\=\dfrac{|\dfrac{-3}{4}|}{\dfrac{11}{2}}\times100\\\\\\=\dfrac{\dfrac{3}{4}}{\dfrac{11}{2}}\times100\\\\\\=\dfrac{3\times2}{11\times4}\times100\\\\\approx14\%

The percent of the estimated time is the actual time is about 14%.
