Question

Suppose in one year, total revenues from digital sales of pop/rock, tropical (salsa/merengue/cumbia/bachata), and urban (reggaeton) Latin music in a certain country amounted to $22 million. Tropical music brought in twice as much as urban music, and pop/rock music brought in $10 million more than the others combined. How much revenue was earned from digital sales in each of the three categories?

pop/rock music ________ $  million tropical music __________   $  million urban Latin music ______ $  million

Explanation / Answer

Tropical music=T, Urban music=U, pop/rock music=R

T+U+R=22

T=2U, R=T+U+10

Solving these three equations, we get

T= 4, R=16 , U=2

Therefore pop/rock music= 16 million

tropical music= 4 million

urban Latin music= 2 million
