    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.
