ANSWER:
16 songs
EXPLANATION:
Given:
Cost of each download = $0.75
Kevin has $25.
After downloading he has a balance of $13.
The equation will be:
0.75x + 13 = 25
where x represents number of MP3 downloaded
To find how many songs he can download, let's solve for x;
0.75x + 13 = 25
Subtract 13 from both sides of the equation:
0.75x + 13 - 13 = 25 -13
0.75x = 12
Divide both sides by 0.75:
[tex]\begin{gathered} \frac{0.75x}{0.75}=\frac{12}{0.75} \\ \\ x\text{ = 16} \end{gathered}[/tex]
Kevin can download 16 songs.
Let's graph the solution on a number line below
