Answer 1

i'm not all too familiar with the constant of proportionality, but both of the situations have a ratio of 0.5/1..

12.50/25 = 0.5/1

17.50/35 = 0.5/1

hopefully this can help you in some way! sorry if it doesn't

Answer 2

k = $0.50

Explanation:

The data that we have is:

Rocko paid: $12.50 for 25 tickets.

Louisa paid: $17.50 for 35 tickets.

Now, the question asks to find the constant of proportionality.

A proportional relation can be written as:

y = k*x

where k is the constant, and in this case, y is the price and x the number of tickets bought.

Then replacing with the values above, we have:

$12.50 = k*25

then:

k = $12.50/25 = $0.50

And the other data:

$17.50 = k*35

K = $17.50/35 = $0.50

So we have the same k in both cases, this means that the constant of proportionality is k = $0.50
