Question

tyler thought the new ipad would cost $259, but it was actually $299. what is tylers percent of error? round to the nearest whole number.

Explanation:

Step1: Calculate the error amount

The formula for error amount is \(| \text{Estimated Value}-\text{Actual Value}|\).
Here, the estimated value \(E = 259\) and the actual value \(A=299\).
The error amount \(=|259 - 299|=| - 40| = 40\).

Step2: Calculate the percent of error

The formula for percent of error is \(\frac{\text{Error Amount}}{\text{Actual Value}}\times100\%\).
Substitute the values: \(\frac{40}{299}\times100\%=\frac{4000}{299}\%\approx13.38\%\).

Step3: Round to the nearest whole number

Since \(13.38\%\approx13\%\) (rounding to the nearest whole number).

Answer:

\(13\%\)
