Answer 1

Percentage error is  $40\%$ .

Step-by-step explanation:

Here we have , Danielle estimates that she will spend $250 on new summer clothes. She actually spent $350. We need to find What is the percent error? Round to the nearest whole percent. Let's find out:

Estimation of Danielle is that she'll spend $250 on new summer clothes.  But ,  She actually spent $350 . So , percentage error is :

⇒ ( final value - initial value )(100) /initial value

⇒ $\frac{350-250}{250} (100)$

⇒ $\frac{100}{250} (100)$

⇒ $\frac{10,000}{250}$

⇒ $\frac{250(40)}{250}$

⇒ $40\%$

Therefore , Percentage error is  $40\%$ .
