Question

Trevor thought there would only be 8 teams in the soccer tournament, but there were 17. What was his percent error?

Answer 1

Around 52.94%

Explanation:

We can use the percentage error formula, which is

`(|approx-exact|)/(exact)\cdot100`.

The approximated value was 8, however the exact value was 17, so we can substitute inside the equation.

`(|8-17|)/(17)\cdot100 \\\\(|-9|)/(17)\cdot100 \\\\(9)/(17)\cdot100 \\\\0.5294...\cdot100 \\\\52.94`

Hope this helped!
