23% error since 70 more people attended then Marcus counted
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.
Marcus counted 230 and 300 actually came.
1. 230-300=-70 but the absolute value is 70
