Answer:
576 People
Solving:
If the total number of people that downloaded songs from the site ( 100% ) equals "x," and 60% of "x" plus 384 equals "x," 384 must be 40% of "x" to add up to 100% ( the percentage of people "x" represents ).
384 / 40% = 960 = x
x = 0.6 ( x ) + 384
960 = 0.6 ( 960 ) + 384
960 * 60% = 576 people
