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 = \(\frac{56+62+x}{3}=$58.80\)
= \(\frac{56+62+x}{3}\times (3)=58.80\times 3\) [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
