Hey There,
@Christo4a
Answer
D. t + 6 = 17
Break the question apart:
"Six of the stations are broadcast below channel 20"
We know six stations are below channel 20
"In a certain city, there are 17 television stations."
We know that there are 17 television stations
We would normally do 17-6 to determine stations which are broadcast at or above channel 20, but there is not an option for that.
The closest answer to the explanation above is D. t + 6 = 17
Hence, answer would be D.
