The answer is 8 because when you replace x by 8 it equals 24
8:15 a.m to 12:45 p.m......4 hrs 30 min
took 45 min lunch (not paid)....now its 1:30 p.m.....
1:30 p.m. to 6:45 pm = 5 hrs 15 min
5 hrs 15 min + 4 hrs 30 min = 9 hrs 45 min or 9 3/4 hrs
$ 16 for first 8 hrs......overtime pay is $ 24 per hr....leaving 1 hr and 45 min or 1 3/4 hrs overtime
16 + 24(7/4) = 16 + 42 = $ 58 <===
The points are
(1,0)
(3,0)
(1,-2)
(5,-2)
put these points on the graph
72 I am guessing because you divide by 3
