You are researching the price of MP3 players. You found an average price of $58.80. One MP3 player costs $56 and another costs $

Butoxors [25]

The price of third MP3 player is $58.40

Step-by-step explanation:

Given,

Cost of one MP3 palyer = $56

Cost of another MP3 player = $62

Average price of MP3 player = $58.80

Let,

Cost of third MP3 player = x

Average = $\frac{Sum\ of\ costs}{Number\ of\ items}$

${58.80}=\frac{56+62+x}{3}$

Multiplying both sides by 3

$3*{58.80}=\frac{56+62+x}{3}*3\\176.40=118+x\\176.40-118=x\\58.40=x\\x=58.40$

The price of third MP3 player is $58.40
