$21 million total; and pop/rock brought in twice as much as the other two combined. That means pop/rock was 2/3 of the total.

(1) pop/rock: 2/3 of $21 million = $14 million

$14 million for pop/rock leaves $7 million for the other two combined.

Pop rock ($14 million) brought in $9 million more than tropical music, so

(2) tropical music: $14 million - $9 million = $5 million

And so

(3) urban: $7 million - $5 million = $2 million
