Answer:
There seems to be a typo in the last part about the primetime commercials. Let's calculate the total duration of the advertising campaign based on the information provided, assuming "three 60-second prime" means three 60-second primetime ads:
Daytime Ads:
Four 30-second ads: 4 ads * 30 seconds/ad = 120 seconds
Three 10-second ads: 3 ads * 10 seconds/ad = 30 seconds
Total Daytime Duration: 120 seconds + 30 seconds = 150 seconds
Primetime Ads:
Three 30-second ads: 3 ads * 30 seconds/ad = 90 seconds
Four 60-second ads: 4 ads * 60 seconds/ad = 240 seconds
Total Primetime Duration: 90 seconds + 240 seconds = 330 seconds
Total Campaign Duration: 150 seconds (daytime) + 330 seconds (primetime) = 480 seconds
Converting to minutes: 480 seconds / 60 seconds/minute = 8 minutes
Therefore, the total duration of the advertising campaign is estimated to be 8 minutes.
