By looking at the graph, we can see that the shape is a quarter of a circle. 
The area of a circle is:

So, this "quarter circle" is:

R is the radius (the diagram shows the radius is 8), so we can now find the area:

The area is 8π.
 
        
                    
             
        
        
        
The given formula is

Therefore

Given:
C = $25,000
V = $12,000
t = 4.5 years
C/V = 0.48
1/t = 0.2222
Therefore

Answer: 15% (nearest integer)
