ONLY NEED HELP WITH E F & G

The Action Toy Company has decided to manufacture a new train set, the production of which is broken into six steps. The demand for the train is units per 40-hour workweek:

Task	Performance Time (seconds)		Predecessors
A	22
B	30		A
C	15		A
D	15		A
E	10		B, C
F	28		D, E

his exercise only contains parts b, c, d, e, and f.

b) Given the demand, the cycle time for the production of the new train set = 30 seconds (round your response to one decimal place).

c) The theoretical minimum number of workstations= 4 (round your response up to the next whole number).

d) Using the longest operation time rule, the assignment of tasks to workstations should be: (Hint: Number workstations sequentially in terms of precedence relationships and combine any applicable tasks.)

Task	Workstation #
A	Station 1

B

Station 2

C

Station 3

D

Station 3

E

Station 4

F

Station 5

Were you able to assign all the tasks to the theoretical minimum number of workstations? No

e) The total idle time per cycle for the process = ???? seconds (enter your response as a whole number).

f) Efficiency with 5 work stations = ??? %

g) If 6 workstations used, efficiency = ??? %
