Answer:
The constant of proportionality is 0.5
Step-by-step explanation:
We are given the following in the question:
Cost of 25 game tickets = $12.50
Cost of 35 game tickets = $17.50
The cost of ticket C(n) is directly proportion to the number of tickets n.
Thus, we can write:
[tex]C(n) \propto n\\C(n) = an[/tex]
where a is the constant of proportionality.
Putting values, we get,
[tex]12.50 = 25a\\\\\Rightarrow a = \dfrac{12.50}{25}\\\\\Rightarrow a = 0.5[/tex]
Thus, the constant of proportionality is 0.5
