6cups of flour will be needed
5*12/4= 15
90/15=6
        
             
        
        
        
For this case we have the following function:
 
 By definition, the average rate of change is given by: 

 We evaluate the function for the given values:
 For x = 7: 

 For x = 14: 

 Then, replacing values we have: 
 
  Answer:
