system is approximately __________ and its utilization is approximately __________.
A.
79.2 percent; 90.5 percent
B.
90.5 percent; 79.2 percent
C.
87.5 percent; 950 employees

A firm produces three products. Product A sells for $60
; its variable costs are $20.
Product B sells for $200; its variable costs are $120. Product C sells for $25; its variable
costs are $10. Last year, the firm sold 1000 units of A, 2000 units of B, and 10,000 units
of C. The firm has fixed costs of $320,000
per year. Calculate the break

7) Machine used to produce a part for a stereo speaker can produce 100 parts per hour.
The factory operates 12 hours per day 7 days a week. Due to routine scheduled
maintenance the firm expects the ma
chine to be in use only 95% of the time. The firm
also expect from it’s knowledge of its operating facility to achieve an operating efficiency
of only 85%. What is the expected weekly output for this part?
A.
6,783 parts
B.
8,400 parts
C.
4,845 parts
D.
7,140 parts
E.
100 parts
Answer: A

14) Which of the following is not one of the four principles of bottleneck management?
A.
Release work orders to the system at the bottleneck's capacity pace.
B.
Lost time at the bottleneck is lost system capacity.
C.
Increasing capacity at non

bottleneck stations is a mirage.

variable costs and revenues increase in direct proportion to the volume of
production
C.
both costs and revenues are made up o
f fixed and variable portions
