Step-by-step explanation:
The total number of listeners of both station combined  =  182,000
Let us assume the number of listens for FM sister station  = M
So, Â the number of listens for AM radio station Â
= 6 x ( number of listens for FM sister station ) Â = 6 Â M
Now,as given,
The number of listener for (AM radio station + Â FM sister station ) Â = 182,000
⇒6  M  + M  = 182,000
or, 7 M = Â 182,000
or, [tex]M = \frac{182,000}{7} = 26,000[/tex]
⇒ M = 26,000
Hence,  the number of listens for FM sister station  = M  = 26,000
The number of listens for AM radio station Â
= 6 M Â = 6 x(26,000) Â = 156,000
