Answer:
No, a value of t = 3.5 does not make any sense in this situation
Step-by-step explanation:
Let
t ----> the number of tickets
c ---> the cost
we have
[tex]c=2.5t[/tex]
This is a proportional relationship between the variables c and t
The slope or constant of proportionality is equal to
[tex]k=\$2.5\ per\ ticket[/tex] ---> is the same that the unit rate
In this problem
The value of t must be a whole number, because you cannot buy a half of ticket
The variable t is a discrete value
