Final answer:
Sammy's ticket sales can be represented using the variable 's' for senior tickets, with 's + 5' for adult tickets and '2 × s' for children's tickets. You sum these numbers for the total tickets sold which equates to the stadium occupancy.
Step-by-step explanation:
Understanding the Ticket Sales Problem
Sammy is selling tickets for the football game and has a certain number for each category of tickets. To represent these, we use variables with 's' representing the number of senior tickets. As given, Sammy sold five more adult tickets than senior tickets which can be represented as (s + 5) for adult tickets, and he sold twice as many children's tickets than senior tickets, which is (2 × s) for children's tickets. To determine the total number of tickets, you would sum the number of senior, adult, and children's tickets.
The number of tickets sold would represent the number of people in the stadium assuming each ticket corresponds to one person, as each ticket has a unique seat number.
