Answer:
a. 
Step-by-step explanation:
The given equation is;
 
To solve by the x-intercept method we need to graph the corresponding function using a graphing calculator or software.
The corresponding function is 

The solution to  is where the graph touches the x-axis.
 is where the graph touches the x-axis.
We can see from the graph  that; the x-intercepts are;
(-1,0),(3,0) and (6,0).
Therefore the real solutions are:

 
        
                    
             
        
        
        
So 2 weeks mean 
250x 2= 500
Then .50 per mile so 500 miles mean
.50 x 500= 250
In total it will be
500+250= 750
