Marcus estimates that 230 people will attend the choir contrary there was an actual total of 300 people who attended the choir concert What is the answer to this?

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

2. 70/300=0.23

3. 0.23 (100) = 23%

Marcus' estimated had a 23% error.
