10 Consider the project information given in Table 17.

TABLE 17 Immediate Expected time Normal Expediting cost Minimum time Activity predecessors (weeks) cost ($) per week ($/week) (weeks)
A — 3 3,000 1,500 2 B — 6 7,200 1,000 4 C A 2 2,000 2,000 1 D A 7 7,000 2,000 3 E C, B 1 4,000 — 1 F B 3 3,000 1,500 2

a. Calculate the project cost based just on the costs of the activities.

b. Generate the weekly and cumulative cash flow charts, once for an early-start schedule and once for a late-start schedule.

c. Discuss the implications of the charts generated in part (b).
