calculate minimum costs, times, and cost schedules

17. Consider the following table of crash times and costs for the above project.

Activity
normal time crash time normal cost crash cost

A 3 1 9000 17000
B 6 3 20000 40000
C 2 1 5000 10000
D 5 3 18000 24000
E 4 3 15000 18500
F 3 1 30000 39000
G 9 4 80000 98000
H 3 2 10000 20000

In the above table normal and crash times are in weeks. Costs are in dollars and represent the costs associated with the job in the specified period. For instance, Phase A will normally take 3 weeks and cost $9000, OR $3000 PER WEEK. To crash the job to one week, the total cost will be $17000 for the week, thus it will cost $4000 for each week crashed.
a. What is the minimum cost to crash the project one (1) week? What activity will be crashed?
b. What is the least amount of time the project can take if fully crashed? What will the project cost fully crashed?
c. Develop a cost schedule for total project cost from finishing in the normal time to maximum crashing, ie. cost to finish in normal time , cost if crashed one week, cost if crashed two weeks, etc. to minimum time to complete.

Use the following data of a firm's total costschedules to calculate its average variable cost, average fixed cost, average total cost, and marginal costschedules.
Output Total Cost Total Variable Cost Total Fixed Cost
1 $2075.00 $ 75.00 $2000.00
2 2140.00

52. The Jones Company has the following cost schedule:
Output Total Cost
(Units) ($)
0 3000
50 3750
100 4275
150 4675
200 5000
250 5300
300 5700
350 6250
400 7050
450 8225
Prepare (a) average total costand (b) marginal costschedules for the firm.

A specialty-freezer company has determined that the operating costs at one of its plants can be approximated by the function:
C = 0.35N2 - 20N + 2000
where C = daily operating cost (dollars) and N = daily production (freezers).
a. Create a data table and graph of this function between N=0 and N=100 freezers. Use a

Suppose that the firm's cost function is given in the following schedule (where Q is the level of output):

2. Given the following total cost schedule of a firm, (a) derive the total fixed costand total variable costschedules of the firm, and from them derive the average fixed cost, average variable cost, average total cost, and marginal costschedules of the firm.

Attached is a past exam question about relevant costs of production, used to deduce the minimum price a company should charge for its product if it is not to make a loss.

You are vice-president of finance of Sandy Alomar Corp., a retail company that prepared 2 different schedules of gross margin for the first quarter ended March 31, 2007. These schedules appear below:
Sales ($5 per unit) cost of goods sold gross margin
Schedule 1 $150,000 12

Information concerning a project is given below. Indirect project costs amount to $250 per day. The company will incur a $100 per day penalty for each day the project lasts beyond day 14.
a) What is the project's duration if only normal times are used?
b) What is the minimum-cost schedule?
c) What is the critical path for the

The market demand function of a firm is given by 8P + Q - 64 = 0, and the firm's average cost function takes the form AC = 8/Q + 6 - 0.4Q + 0.08Q2.
