Answer:
To find the percentage of the money collected from entry fees over the 3 days that was collected on Day 2, we need to first find the total amount collected for all three days.
Total amount collected = $750 + $400 + $300 = $1450
Then, we need to find what fraction of the total was collected on Day 2:
Amount collected on Day 2 = $400
Fraction of total collected on Day 2 = $400 / $1450
Finally, we convert the fraction to a percentage:
Fraction of total collected on Day 2 = $400 / $1450 = 0.2759
Percentage of total collected on Day 2 = 0.2759 x 100% = 27.59%
Therefore, approximately 27.59% of the money collected from entry fees over the 3 days was collected on Day 2.
