greg is considering 2 different plans for music downloads. how many tracks purchased would make plan A the better option?

PLAN A:
$0.97 per track purchased plus
$10.00/ month unlimited PC streaming plus $15.00/month for downloading songs to an MP3 player

PLAN B:
$0.99 per track purchased plus
$9.00 month unlimited PC streaming plus $144.00/year for downloading songs to an MP3 player.

If A is better, we need

25+.97n < 21+.99n
because $144/yr is $12/mo
4 < .02n
n > 200
