Answer:
Approximately needed:
He can download at most 16 songs to leave $13 for himself to spend.
Use the equation $25-$0.75(x)=$13
We can break this complicated looking shape into two more familiar ones, an icosoles triangle and a rectangle. Using the area of a triangle formula (base*height)/ 2, we get (3*6)/2=18/2= 9. Next, we multiply 8 by 16 to solve for the rectangle and get 128. We add 9 and 128 to get 137.
Your answer is 137.
