Answer:
The System of inequality is , 
1. y > 2 x + p
2. y < 2 x + p
Suppose we assign some values to p and q and draw its graph
And, then the inequality sign on both inequalities is reversed 
3. y < 2 x + p
4. y > 2 x + p
And , then draw it's graph
it has been found that, the solution set of both the inequality remains same.That is there is no point or set of points , which satisfy both the system of inequality.
The system has no solution.
 
        
                    
             
        
        
        
291-186=105 (total earned through wages) 
105/5=21 
Therefore she worked 21 hours
