Question

Ron is planning for the back to school rush at his store. Last year he estimated that he would need 168 notebooks. Explain how Ron can find the percent error of his estimate

Answer 1

To calculate the percent error, he will need the real value and the estimated value.

In this problem, we only know the value of the estimated value.

If we would know both values just substitute them in the equation and solve for percent error.

`\text{ Percent error = }\frac{estimated\text{ value - real value}}{estimated\text{ value}}\text{ x 100}`
