Question

The price of the tennis racket was 200 dollars. However, the actual price of the tennis racket was 400 dollars. What is the percent error?

Answer 1

Given,

The price of the tennis rocket = $200

The actual price of the tennis racket was $400

To find,

The percentage error in the price of the rocket.

Solution,

The percentage error is calculated as :

% = (final value-actual value)/actual value × 100

`\%=(400-200)/(400)* 100\\\\=50\%`

So, the percent error is 50%.
