To fill in the table based on the information that each student receives 20 tickets, we can use the formula:
\[ \text{Number of tickets (t)} = \text{Number of students (s)} \times \text{Tickets per student} \]
Given that each student receives 20 tickets, we can calculate the number of tickets for different numbers of students:
-
For 2 students: \[ t = 2 , \text{s} \times 20 , \text{tickets per student} = 40 , \text{tickets} \]
-
For 4 students: \[ t = 4 , \text{s} \times 20 , \text{tickets per student} = 80 , \text{tickets} \]
-
For 6 students: \[ t = 6 , \text{s} \times 20 , \text{tickets per student} = 120 , \text{tickets} \]
-
For 8 students: \[ t = 8 , \text{s} \times 20 , \text{tickets per student} = 160 , \text{tickets} \]
Now, let's fill in the table with the values:
| Number of students (s) | Number of tickets (t) | Tickets per student | |------------------------|-----------------------|---------------------| | 2 | 40 | 20 | | 4 | 80 | 20 | | 6 | 120 | 20 | | 8 | 160 | 20 |
This table shows the total tickets based on the number of students who show their school IDs.
