You can put this solution on YOUR website! The sales of records, tape cartridges, and cassettes form the ration 3:4:6, respectively. In a display of 65 items, how many of each kind should be included to match the customers' typical preference?
-------------
3:4:6 is the same as 3x:4x:6x
----------------
EQUATION:
3x+4x+6x=65
13x = 65
x = 5
records = 3x = 15
tape carts = 4x = 20
cassettes = 6x = 30
