Answer:

24 minutes

Step-by-step explanation:

we have information:

minutes of TV      minutes of commercials

     30                 ⇒              8

and we want know how many minutes of commercials there are in 90 minutes of TV:

minutes of TV      minutes of comercials

     30                 ⇒              8

     90                 ⇒              x

where x is the number of minutes of commercials, we solve this by the rule of three: multiply the cross quantities (90 by 8) and then divide by the amount we haven't used (30), like this

[tex]x=\frac{90*8}{30}=\frac{720}{30}=24[/tex]

the answer is: 24 minutes
