Solve the problem.

During a 30-minute television show there are 4 commercial breaks. Each break has 3 commercials that are each 30 seconds long. The show is on twice a week. How long does the show itself last?

________minutes

Each break lasts [tex]3\cdot 30=90[/tex] seconds that is 1.5 minutes. There are 4 commercial breaks. Total length of these breaks is [tex]1.5\cdot 4=6[/tex] minutes.

If there are 4 commercial breaks, then there are 5 parts of show (part-break-part-break-part-break-part-break-part). Each show lasts

[tex]5\cdot 30+6=156[/tex] minutes.

The show is twice a week, so the show lasts

[tex]156\cdot 2=312[/tex] minutes
