Note: We need to find the number of total box tops instated of total number of cans.
Given:
Trinity collected 36 box tops.
Peyton collected [tex]1\dfrac{1}{2}[/tex] times as many as Trinity.
To find:
The number of box tops they did collect all together.
Solution:
It is given that,
Number of box tops collected by Trinity = 36
Number of box tops collected by Peyton = [tex]1\dfrac{1}{2}\times 36[/tex]
= [tex]\dfrac{3}{2}\times 36[/tex]
= [tex]54[/tex]
Total = [tex]36+54[/tex]
= [tex]90[/tex]
Therefore, the total number of box tops collect all together is 90.
