Salesperson Estimated Sales for the Week Actual Sales for the Week

$380
Deanne

Answer 1

Using the percent error concept, it is found that:

• Hector, Deanne and Samantha had errors of less than 20%.

• Ben had a error of more than 20%.

What is the percent error?

• The percent error of an amount is the absolute value of the difference between the actual amount and the expected amount, multiplied by 100% and divided by the expected amount.

Hence, the percent error of each person is given by:

$P_{H} = \frac{|525 - 625|}{625} \times 100\% = 16\%$

$P_{B} = \frac{|380 - 310|}{310} \times 100\% = 22.58\%$

$P_{D} = \frac{|700 - 775|}{775} \times 100\% = 9.68\%$

$P_{S} = \frac{|205 - 250|}{250} \times 100\% = 18\%$

Hence:

• Hector, Deanne and Samantha had errors of less than 20%.

• Ben had a error of more than 20%.
