Respuesta :
58.5 x 3 = 176.4
176.4-56-62 = 58.4
therefore the 3rd MP3 player costs $58.4
176.4-56-62 = 58.4

Answer:
$58.40
Step-by-step explanation:
The average price of MP3 player = $58.80
Price of one MP3 player = $56
cost of second MP3 player = $62
Let the third MP3 player costs = x
average price = [tex]\frac{56+62+x}{3}=$58.80[/tex]
= [tex]\frac{56+62+x}{3}\times (3)=58.80\times 3[/tex] [multiply both side by 3]
52 + 62 + x = 176.40
x + 118 = 176.40
x = 176.40 - 118
x = 58.4
The price of the third MP3 player would be $58.40
Check :
[tex]\frac{(56+62+58.4)}{3}[/tex]= 58.80
= [tex]\frac{176.40}{3}[/tex] = 58.80
= $58.80
