A warehouse supply worker accidentally misreads the number 75 as 57. What percent change did the reading error result in?
snow_lady [41]

The percent change is 24 % due to reading error

<em><u>Solution:</u></em>

Given that a warehouse worker misread the number 75 as 57

To find: percent change due to reading error

<em><u>Step 1:</u></em>

Find the difference between the correct number and misread number

75 - 57 = 18

<em><u>Step 2:</u></em>

Calculate the percentage change due to reading error

\text{ Percent change }= \frac{difference\ between\ numbers}{correct\ number} \times 100

Percent\ change= \frac{18}{75} \times 100

\rightarrow \frac{18}{75} \times 100 = 0.24 \times 100 = 24

Thus the percent change is 24 % due to reading error
