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
