Be precise, find the percent error:
Marcus estimates that 230 people will attend choir concert. There was an actual total if 300 people who attended the choir concert.
(300 - 230)/230 = ?
Multiply the decimal answer by 100.
23.3333%
(300-230)/300
70/230*100=23.3333
That's not what I get. How did you arrive at 23.3333%?
(300 - 230)/230 =
Right.

To find the percent error, you need to compare the estimated value with the actual value and then calculate the difference as a percentage of the actual value. Here's how you can do that:
Step 1: Calculate the difference between the estimated value and the actual value.
Estimated Value: 230
Actual Value: 300
Difference = Actual Value - Estimated Value = 300 - 230 = 70
Step 2: Calculate the percent error.
Percent Error = (|Difference| / Actual Value) x 100
Percent Error = (|70| / 300) x 100
Percent Error = 0.2333 x 100
Percent Error ≈ 23.33%
Therefore, the percent error in Marcus's estimation of the number of people attending the choir concert is approximately 23.33%.
