To find the best estimate of the number of notices Kaylee must fold each day to meet her goal of 586 notices in 22 days, we can approximate the numbers involved.
- Since Kaylee needs to fold 586 notices, we can round this number. Rounding to the nearest hundred gives us 600.
- She has 22 days to complete this task.
Now, if we want to find out how many notices she needs to fold each day, we will use the expression \(600 \div 20\) (as 20 is the nearest round number to the number of days).
Here's the reasoning for the options:
- A: \(500 \div 20\) - This would estimate how many she would fold if she only needed 500 notices, which isn't accurate.
- B: \(500 \div 30\) - Again, this uses the wrong total (500) and the wrong division (30 days).
- C: \(600 \div 20\) - This gives us an estimate based on a rounded total of 600 notices and 20 days to fold them.
- D: \(600 \div 30\) - This uses a total of 600 but wrongly assumes 30 days instead of 22.
Therefore, the best expression for estimating the number of notices Kaylee must fold each day is:
C: \(600 \div 20\).
