Sue Helms Appliances wants to establish an assembly line to manufacture its new product, the Micro Popcorn Popper. The goal is to produce

five

poppers per hour. The tasks, task times, and immediate predecessors for producing one Micro Popcorn Popper are as follows:

Task	Performance Time (mins)	Task Must Follow Task Listed Below
A	9
B	10		A
C	8		A, B
D	9		B, C
E	7		C
F	5		D, E

F

B

E

D

In the diagram, there are 6 circles labeled using the letters from A to F. There are 8 of arrows, and each arrow connects one circle to another circle. The arrows are situated in the following manner: A to B, A to C, B to C, C to D, B to D, C to E, D to F, and E to F.
