two movie tickets cost 19.00. three movie tickets cost 28.50 what is the costant of proportionality?

1) 0.5

2) 9.0

3) 9.5

4) 11.0

What is the answer? This is very confusing... Maybe I will put it here when I finish the practice for future viewers.

thanks

To find the constant of proportionality, we need to determine the relationship between the number of movie tickets and their cost. We can do this by calculating the cost per ticket for each scenario.

Let's start by determining the cost of one movie ticket in the first scenario, where two tickets cost $19.00. We divide the total cost ($19.00) by the number of tickets (2):
Cost per ticket = $19.00 / 2 = $9.50

Now, let's calculate the cost per ticket in the second scenario, where three tickets cost $28.50. We divide the total cost ($28.50) by the number of tickets (3):
Cost per ticket = $28.50 / 3 = $9.50

We can see that the cost per ticket in both scenarios is the same, which means the cost per ticket remains constant. Therefore, the constant of proportionality is $9.50.

So, the correct answer is option 3) 9.5.
