Question

One month, a music site observed that 60% of the people who downloaded songs from its site downloaded Q Sam's latest single. The equation below represents this information, where x represents the total number of people who downloaded songs from the site that month.

x = 0.6x + 384

How many people who downloaded songs from the site that month downloaded Q Sam's latest single?
Answer

144

576

960

240

Answer 1

0.4 x = 384
x = 960
So 0.6x = 576.
Answer: 576 people.

Answer 2

First, you need to find x, which is the total number of people who downloaded music that month.

1x = 0.6x + 384
1x - 0.6x = 384
0.4x = 384
0.4x/0.4 = 384/0.4
x = 960

Now you have to look back at the question, which says that 60% of people downloaded this song. Simply take 60% of the value of x.

960 x 0.6 = 576.
