The price of each ticket is $42.50. So if Selene buys x tickets, the cost of x tickets will be 42.50x.
She has to pay $5 handling fee as well for purchasing the tickets online. So her total cost of the tickets will be:
Total Cost = 42.50x + 5
Selene got $250. This means she can spend a maximum of $250 on the tickets. Maximum of $250 means less than or equal to $250.
So, we can write the spending on the tickets in the form of following in equality:
42.50x + 5 ≤ 250
42.50x ≤ 245
x ≤ 5.76
This shows, Selene can buy 5.76 tickets. Since the number of tickets has to be a whole number we look for the nearest possible number. She cannot buy 6 tickets, as the cost will exceed $250. So the maximum tickets she can buy are 5.
