Question

jeanscah estimates that 475 songs will fit on her iphone.the actual amount of the songs that fit Is 380.find the percent error.

Answer 1

Data:

Estimate: E= 475 songs

Actual amount: A=380

To find the percent of error you use the next formula:

`\text{error}=(\mleft|E-A\mright|)/(A)\cdot100`
`\begin{gathered} \text{error}=(\mleft|475-380\mright|)/(380)\cdot100 \\ \text{error}=(\mleft|95\mright|)/(380)\cdot100 \\ \text{error}=0.25\cdot100 \\ \text{error}=25 \end{gathered}`Then, the percent error is 25%
