Respuesta :

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