100 students were estimated at a basketball game. 120 students
were actually there. What is the
percent error?

20%

Step-by-step explanation:

Use the formula:

The "|" symbol represents absolute value and the dashed line represents a division line.

                         | Theoretical Value - Actual Value |

Percent Error =   × 100

                         |              Theoretical value              |

100 - 120 = -20

-20 / 100 = -0.2

|-0.2| = 0.2

0.2 × 100 = 20

The answer is 20%
