Purchased Bonus Tickets (P) Tickets (B) 3 9 8 15 25 The head is equal to 4 arms 22 28 33 It is also important to state the inverse relationship: 45 81 1 arm is equal to ¼ of the head Complete the table with your students. Guide them through the process as needed. Now a look at another type of table. let’s take The carnival is offering bonus tickets with every purchase of carnival tickets. The table below shows the different numbers of tickets purchased and the number of bonus tickets that are given.
