Jeremy goes to the circus. He thinks he will need $30 for the rides but he only spends $19.75. Find the percent error. Round to the nearest whole number.

Answer 1

The percent error is calculated by taking the absolute difference between the expected value and the actual value, dividing it by the expected value, and then multiplying by 100%.

The expected value is $30 and the actual value is $19.75.

The absolute difference is |30 - 19.75| = $10.25.

So the percent error is (10.25/30) * 100% = 34.17%.

Rounded to the nearest whole number, the percent error is 34%. Answer: \boxed{34}.
