Each commercial is either 30 or 60 seconds long. If the total commercial time during 1 hour is 8 minutes, how many 30-second and how many 60-second commercials were played that hour?

I have found a couple on the internet but they look pretty easy to build yourself and probably cheaper. If anyone knows the specs on how to build one, i would appreciate it if you would fill me in on this.
