Question: Two teams are playing in a stadium with a capacity of 2000 people. The total number of people in the stadium is 3/4 of the total capacity and each person paid $20 in entry fees. What is the difference between the total amount of fees collected when the stadium was 3/4 full and if the stadium would have been full? Think carefully first, then make a decision:
When the stadium is full, the total fees charged is 2000 * $20 = $40000. When the stadium is 3 / 4 full, the total number of people in is 3 / 4 * 2000 = 1500 people. The total entry fees collected when the stadium is 3 / 4 full is 1500 * $20 = $30000. The difference in the total entry fees when the stadium is full and when it's 3 / 4 full is $40000 - $30000 = $10000. So the answer is 10000.
