Answer:
k = 12
Step-by-step explanation:
Given in the question,
Cost of the the movie tickets is proportional to the number of tickets sold.
Cost of movie tickets (C) ∝ number of tickets sold (T)
C ∝ T
C = kT
Here 'k' is a proportionality constant.
Since, line given in the graph passes through a point (5, 60)
60 = k(5)
k =
k = 12
Therefore, value of proportionality constant is 12.
