Perimeter of a triangle = sum of measures of each side ; 


 
        
                    
             
        
        
        
Let x be Juilo's normal hourly rate.
so for the 35 hr week  we have:-
30x + 5*1.4x = 436.60
37x = 436.60
x = 436.60 / 37 =  $11.80
His normal hourly rate = $11.80
So for a 30 hr week he will earn 11.80 * 30  =  $354
So  the  amount $436.60  is a reasonable figure for  a 35 hr week.
        
             
        
        
        
The estimated probability would be 0.1... I had this test yesterday. hope this helps
