Graph. red• 25+0.5d (music city)
blue•. 1.5d

Music city
C=25+0.5d
C-cost
D-downloads

Both are the same cost at 25 downloads
$c = 25 + 0.5d \\ c = 25 + 0.5(25) \\ c = 25 + 12.5 \\ c = 37.5$
Tune Dune
C=1.5d
$c = 1.5d \\ c = 1.5(25) \\ c = 37.5$
Tune Dune is cheaper until the 25 song downloaded, the they are equal. After that, Music city is cheaper.
