A customer walks into an electronics store and buys five MP3 players and eight sets of headphones,?
paying $840. A second customer buys three MP3 players and four sets of headphones, and pays $480. How much does an MP3 player cost? How much does a set of headphones cost?
You have to solve a set of equations:
5x+8y=840
3x+4y=480
where x – price of an MP3 player and y – price of a headphones set.
Solution x=120$ y=30$
