Question

Answer 1

Given:

Ava estimates that 475 songs will fit on her iPad.

The actual amount of songs that fit is 350.

To find:

The percent of error.

Solution:

We know that,

$\text{Percent error}=\dfrac{\text{Estimated values - Actual value}}{\text{Actual value}}\times 100$

Putting the given values, we get

$\text{Percent error}=\dfrac{475-350}{350}\times 100$

$\text{Percent error}=\dfrac{125}{350}\times 100$

$\text{Percent error}=\dfrac{250}{7}$

$\text{Percent error}\approx 35.71\%$

Therefore, the percent of error is 35.71%.
