Explanation:
From the given graph;
The price for digital downloads of music per music, can derived from the graph.
price per music is the slope of the graph;
[tex]\begin{gathered} c=\frac{\Delta p}{\Delta n}=\frac{6-2}{8-0}=\frac{4}{8} \\ c=0.50\text{ dollars/song} \end{gathered}[/tex][tex]f(x)=0.50x[/tex]
To download two music;
[tex]\begin{gathered} F=2\times0.50 \\ F=\text{ \$1.0} \end{gathered}[/tex]
From the function g(x); the total cost for movie download is;
[tex]g(x)=2x[/tex]
the price per movie is;
[tex]\text{ \$2.0}[/tex]
To download two movies;
[tex]\begin{gathered} G=2\times\text{ \$2} \\ G=\text{ \$4.0} \end{gathered}[/tex]
