it was estimated that 400 people v would attend the game but 388 people actually attended.

what's the percent error to the nearest percent?

To find the percent error, we use the formula:

Percent Error = (|Estimated Value - Actual Value| / Estimated Value) * 100

In this case,
Estimated Value = 400
Actual Value = 388

Substituting these values into the formula, we get:
Percent Error = (|400 - 388| / 400) * 100
= (12 / 400) * 100
= 0.03 * 100
= 3%

Therefore, the percent error to the nearest percent is 3%.
