Amelio Rodriguez Computing wants to establish an assembly line for producing a new product, the Personal Digital Assistant $($PDA$).$ The tasks, task times, and immediate predecessors for the

tasks are as follows:

Amelio's goal is to produce $175$ PDAs per hour.

a$)$ The cycle time for the production of a PDA $=20\mathrm{.}57$ seconds $($round your response to two decimal places$).$

b$)$ The theoretical minimum number of workstations that Amelio can achieve in this assembly line $=3($round your response up to the next whole number$).$

c$)$ For one to assign the tasks to the actual workstations and be able to use the "theoretical minimum" number, the activity assignment should be:

Were you able to assign all the tasks to the theoretical minimum number of workstations?
