A project network is shown below. All activity times are given in days. Suppose C could be shortened by three days (i.e., C takes 3 days to complete instead of 6) and F could be shortened by one day (i.e., F takes 7 days instead of 8). With these changes in activity times of C and F, how long will it take to complete the project?

Question 8

A manufacturer has decided to locate a new factory in the northwest U.S. to serve growing demand in that market and has narrowed the potential sites down to two finalists, City X and City Y. The manufacturer developed a list of important factors to consider in selecting the site. Next, each city was rated against each factor as shown in the following table. According to the Factor-Rating method, which city should the manufacturer select?

Factors	City X	City Y
Utility rates	100	110
Availability of skilled labor	78	75
Tax rates	40	30
Transportation	46	38
Proximity to suppliers	35	29
Quality of life	19	16

Question 8 options:

	City Y
