  2. $571,000
  3. $518,200
  4. $552,000
  5. $578,750
Explanation

Answer: B - $571,000. $4 million divided by 7 days is an average of $571,429 per day.

Key Takeaway: Dividing by seven and estimating by 7 is an important skill because of the week unit is frequently used. If you remember the repeating decimal below, all you have to do is move it over in this question. Alternatively, remember the first 2 numbers to speed up estimations.  

1/7 = .142857
2/7 = .285714
3/7 = .428571
4/7 = .571428
5/7 = .714285
