Average price of a CD/ mp3 player is : $ 150
Meanwhile , average price of an mp3 player is : $50
To buy 4 cd/mp3 player, we need $ 150 x 4 = $ 600
To but an mp3 player, we need $50 x 3 = $ 150
The total is $ 750
Hope this helps
Answer:
If there are 12 white horses in 5 a herd of 52 horses, there will be 40 black horses if there aren't any other color horses.
The ratio will be 40 : 12
To simplify, it will be 10 : 3
The picture is really blurry
The first number would be 6 and the second would be 24
x+4x=30, in which x=6
Hope this helped :)
