Question

Rocko paid $12.50 for 25 game tickets.

Answer 1

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:

$C(n) \propto n\\C(n) = an$

where a is the constant of proportionality.

Putting values, we get,

$12.50 = 25a\\\\\Rightarrow a = \dfrac{12.50}{25}\\\\\Rightarrow a = 0.5$

Thus, the constant of proportionality is 0.5
