Answer:
13.82 or 14 people
Step-by-step explanation:
Step 1: Set equation equal to 7500
7500 = -25x² + 1250x - 5000
Step 2: Solve
0 = -25x² + 1250x - 12500
0 = -25(x² - 50x + 500)
0 = x² - 50x + 500
When you use the quadratic formula, you should get 13.82, rounded to 14 people as your answer.
Alternatively, we can graph the expression and see where $7500 for <em>x</em> people is.
