Answer:
Step-by-step explanation:
A.123.50≤20+10(x)
103.50≤10x
10.35 hours at least to equal the 123.50.
10.35 hours *10 an hour is 103.50+20 flat fee=123.50
B. 123.50≤15(x)
8.24 hours or more. 15.00 an hour at 8.24 hours = 123.60
C. He will work less hours if he charges more and does not charge the flat fee.
 
        
                    
             
        
        
        
The line in the middle has a right angle, so the angle just above the Y would be 90 degrees.
 The angle to the right of y is given as 48.
The three inside angles of a triangle need to equal 180.
 So y  = 180 - 90 - 48 = 42 degrees.
