Answer:

For 90 minutes of TV there will be 24 mins of commercials


Step-by-step explanation:

You start with 30 and keep adding 30 mins each time until you get to 90. (So..30..60..90) each time you add 30mins you add 8 more minutes to the commercials)

30 mins tv----8mins commercials

60 mins tv----16mins commercials

90 mins tv----24mins commercials


Hope this helps, good luck!
