Your are researching the price of MP3 players. You found an average price of $58.80. One MP3 player costs $56 and another costs $62. Find the price of the third MP3 player.
The sum of the 3 players needs to be 176.4$ since there are 3 players.(58.8$x3players) Since you already know 2 prices, you add them both up (56+62=118) and subtract the total by the 2 players (176.4$-118=58.4). Your answer should be 58.4$.
