Answer

Explanation:

Step1: Recall percent - error formula

Percent error = $\left|\frac{\text{Estimated}-\text{Actual}}{\text{Actual}}\right|\times100%$

Step2: Calculate percent - error for Alan

Percent error for Alan = $\left|\frac{300 - 340}{340}\right|\times100%=\left|\frac{- 40}{340}\right|\times100%\approx11.76%$

Step3: Calculate percent - error for Bianca

Percent error for Bianca = $\left|\frac{485 - 575}{575}\right|\times100%=\left|\frac{-90}{575}\right|\times100%\approx15.65%$

Step4: Calculate percent - error for Christos

Percent error for Christos = $\left|\frac{515 - 450}{450}\right|\times100%=\left|\frac{65}{450}\right|\times100%\approx14.44%$

Step5: Calculate percent - error for Declynn

Percent error for Declynn = $\left|\frac{260 - 230}{230}\right|\times100%=\left|\frac{30}{230}\right|\times100%\approx13.04%$

Step6: Calculate percent - error for Ellema

Percent error for Ellema = $\left|\frac{315 - 390}{390}\right|\times100%=\left|\frac{-75}{390}\right|\times100%\approx19.23%$

A. Alan C. Christos D. Declynn
