100 tickets were sold.
The total amount of the tickets sold is = 5 * 100 = $500.
First prize given = $100
Second prize worth = $20 * 5 = $100
Total worth of prize + $100 + $100 = $200.
Net amount of tickets sold = $500 - $200 = $300
Expected price of each ticket sold = $300/100 = 3.
Therefore, the real price of each ticket sold is $3.
The vertex is the lowest/highest point, depending on if the parabola opens upwards or downwards.

in not sure if it would be correct but i think it would be c because the lines would eventually cross through eachother
