Answer:
14 to 46 tickets
Step-by-step explanation:
Step 1: Set up the equation
500 ≤ -2x² + 120x - 788
Step 2: Solve for <em>x</em>
0 ≤ -2x² + 120x - 1288
0 ≤ -2(x² - 60x + 644)
0 ≤ x² - 60x + 644
0 ≤ (x - 46)(x - 14)
14 ≤ x ≤ 46
Alternatively, we can graph the equation and determine the range by looking for where y = 500
