Answer:
18 minutes 34.8 seconds
Step-by-step explanation:
We assume the minutes of commercials are proportional to the minutes of television, so we have ...
(6 minutes of commercials)/(6 + 25 minutes of television) = x/(96 minutes of television)
Multiplying by 96, we get ...
x = 96·6/31 = 576/31 = 18 18/31 . . . . minutes of commercials
That's about 18 minutes, 34.8 seconds of commercials in 1 hour 36 minutes of television.
