Easy! Just multiply 7 1/3 by 8 which leaves you with 58 2/3. Now, that 1/4 is 1/4 of an hour. If you can fill 7 1/3 boxes in 1 hour, how many can you fill in 1/4? 7 1/3 divided by 1/4 is 29 1/3. Add them together. 81 boxes.
49.5-40 = 9.5
so 40 x 8.18 = 327.20
8.18 x 1.5 = 12.27
12.27 x 9.5 = 116.57
327.20 + 116.57 = $443.77
