Answer:the constant of proportionality is 2.5

the number of hours that

Bruno would have listened after 12 days is 30

Step-by-step explanation:

Let x represent the number of days.

Let y represent the total number of hours.

Bruno listens to podcasts for

two and a half hours a day.

Let k represent the constant of

proportionality. It means that

k = y/x = 2.5/1

k = 2.5

The expression becomes

y = 2.5x

Therefore, the number of hours that

Bruno would have listened after 12 days would be

y = 12 × 2.5 = 30 hours
