5. A Virginia county is considering whether to pay $50,000 per year to lease a prisoner transfer facility in a prime location near Washington, D.C. They estimate it will cost $50 per prisoner to process the paperwork at this new location. The county is paid a $75 commission for each new prisoner they process. What would be the county’s annual profit if they were to process 4,000 prisoners per year at this new location?
To compute, get the product of the number of prisoners and the $75 commission. Then, subtract the product of the number of prisoners and the estimated paperwork cost. Lastly, subtract the $50,000 needed to be paid per lease. Hence, the counties annual profit would be:
Annual Profit = $75 × $4,000 – $50 × $4,000 – $50,000
= $300,000 – $200,000 – $50,000
= $100,000 – $50,000
Annual Profit = $50,000
Therefore, the correct answer for the question is the third option: $50,000.

10. A company needs to locate three departments (X, Y, and Z) in the three areas (I, II, and III) of a new facility. They want to minimize interdepartmental transportation costs, which are expected to be $.50 per load per meter moved. An analyst has prepared the following distances and flow matrices:
From/To I II III
I – 10 20
II – 10
Flows (loads per week)
From/To X Y Z
X – 60 90
Y 40 – 160
Z 110 140 –
What is the total flow (loads per week) between department Y and department Z?
Answer: Total Loads(Y,Z) = loads (YZ) + loads (ZY) = 160 + 140 = 300 loads
11. A methods and measurements analyst needs to develop a time standard for a certain task. In a preliminary study, he observed one of his workers perform this task five times, with the following results:
Observation 1 2 3 4 5
Time(Seconds) 84 76 80 84 76
What is the standard time for this task if the employee worked at a 25 percent faster pace than average and an allowance of 20 percent of job time is used?
12. In a stopwatch time study, the number of cycles that must be timed is a function of:
(I) the variability of observed times.
(II) the desired accuracy for the estimated job time.
(III) the desired level of confidence for the estimated job time.
Answer: the variability of observed times.
13. The manager of Lawn and Garden Services would like to estimate the proportion of her employees’ time spent performing various gardening and lawn care activities. She has made 400 random observations of a typical worker, with the following results:
Activity Time Observed
Between what limits can the manager be 68.26 percent confident about the true proportion of time spent mowing?
14. A methods and measurements analyst for Timepiece, Inc., needs to develop a time standard for the task of attaching a watch to a wristband. In a preliminary study, he observed one of his workers perform this task five times, with the following results:
Observation 1 2 3 4 5
Time(Seconds) 27 19 20 21 13
What is the standard time for this task if the employee worked at a 20 percent faster pace than average, and an allowance of 20 percent of the workday is used?
A. 24 seconds
B) 25 seconds
C) 30 seconds <–
D) 20 seconds
E) 28.8 seconds
Answer: ST = NT x AF
AFday = 1/1-A
NT = OT x PR
OT = Mean
PR = 1.2
NT = 20 x 1.2 = 24
AFday = 1/1-.2 = 1.25
ST = 24 x 1.25 = 30
15. Which of the following is not an advantage of time-based pay systems?

Answers: regional factors
19. A location analysis has been narrowed down to three locations. The management needs to select the best location. The critical success factors, their weights, and the ratings for each location are shown below:
|Raw Materials Cost||0.1||75||70||90|
a) The composite score for location A is _____
b) The best location is _____
Answer and Explanation:
The formula for determining composite score is:
a) Calculation of Location A’s composite score:
|Factors||Weights (A)||Location A rating (B)||Composite Score (A*B)|
|Raw material costs||0.1||75||7.5|
Location A’s composite score is 78.4
b) The determination of the composite score is essential to determine the best location, so the locations B and C’s composite scores are as follows:
Location A composite score is 78.4
Calculation of Location B’s composite score
|Factors||Weights (A)||Location B rating (B)||Composite Score (A*B)|
|Raw material costs||0.1||70||7|
Location B’s composite score is 79.5
Calculation of Location C’s composite score
|Factors||Weights (A)||Location C rating (B)||Composite Score (A*B)|
|Raw material costs||0.1||90||9|
Location C’s composite score is 82.
Therefore, Location C is the best location.
