I was doing the problem yesterday but I totally forgot how to do the second part.
Pop station : listeners 85k ; cpm $14 ; % of listeners in target market 20%.
I did 14X85= 1190. I forgot the next step but the answer is .07. I think I have to divide something but I'm blanking.
?? You "did 14X85= 1190" to answer what[$/b] question? The answer to what question "is .07"? What does "cpm" mean? If "cpm" is "cost per million listeners" then the "total cost" is .85 X 14= $11.90. Is that what you did??
