Answer:
Number of tickets is proportional to cost of tickets.
Step-by-step explanation:
The question was silent not telling us what to do with the given information.
Assuming determine whether the relation is proportional.
If the number of tickets is proportional to the cost, then its equation must be of the form:
[tex]y = mx[/tex]
We substitute , x=4, y=78 to solve for m.
[tex]78 = 4m[/tex]
This implies that:
[tex]m = \frac{78}{4} = 19.5[/tex]
Therefore the relation is
[tex]y = 19.5x[/tex]
When x=1, we get y=19.5
Therefore number of tickets is proportional to cost
