Gregory predicts that 310 people will attend the spring play there was an actual total of 220 people who attended the spring play. What is the percent error round to the nearest whole percent

41%

Step-by-step explanation:

To calculate the percent error:

We find the difference between the predicted and the actual. We divide the absolute value of the difference by the actual recorded value. Convert to a percent by multiplying by 100 and adding a % sign.

Gregory predicted 310 and 220 actually came.

1. 310-220=90

2. 90/220=0.41

3. 0.41 (100) = 41%
