You and your friends go to the movies. The cost of admission is 9.50 per person. Create a table showing the relationship between the number of people going to the movies and the total cost of admission. Explain why the cost of admission is proportional to the amount of people.

Answer 1

Its like rate its a constant value increasing

Answer 2

Number of persons Total cost $

1 9.50 * 1 = 9.50

2 9.50 * 2 = 19.0

3 9.50 * 3 = 28.5

4 9.50 * 4 = 38.0

10 9.50 * 10 = 95.0

20 9.50 * 20 = 190.0

x 9.50 * x

The cost of admission is proportional to the amount of people because it is a constant value (9.50) times de number of persons:

Cost = K * x, where K = 9.50

That is what is know as proportional relationship.
