Question

A movie theater has increased their ticket prices. They are shown below

Answer 1

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 = $\frac{60}{5}$

k = 12

Therefore, value of proportionality constant is 12.
