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?

576

240

144

960

Answer 1

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.

\[960 x 0.6 = 576\]

Answer 2

960*0.6=576 i meant in the last one
