Part A
Let x represent the number of coworkers who prefer the talk news radio.
[tex]65[/tex]% prefer the talk news radio,
[tex]100-65=35[/tex]% will be the percentage that corresponds to coworkers who do not prefer the talk news radio.
Part B
We apply ratio to find x.
[tex]65:x[/tex]
[tex]35:28[/tex]
Hence number that corresponds to 65% will be greater than 28.
If more, less will divide.
This implies that,
[tex]x=\frac{65\times 28}{35}=52[/tex]
Hence 52 of her coworkers prefer the local news talk station.
