Answer to Question 1
1. Indirect costs = 10,000
Total professional labor-hours = 250 hours (150 hours on Campa Coal + 100 hours on St. Edith's Glass)
Indirect cost allocated per professional labor-hour (revised) = 10,000 250 = 40 per hour
2. Campa St. Edith's
Coal Glass Total
Direct costs:
Direct professional labor,
80 150; 80 100 12,000 8,000 20,000
Research support labor 1,800 3,850 5,650
Computer time 400 1,600 2,000
Travel and allowances 700 4,200 4,900
Telephones/faxes 250 1,200 1,450
Photocopying 300 700 1,000
Total direct costs 15,450 19,550 35,000
Indirect costs allocated,
40 150; 40 100 6,000 4,000 10,000
Total costs to be billed 21,450 23,550 45,000
3.
Campa St. Edith's
Coal Glass Total
Problem 5- 30 27,000 18,000 45,000
Problem 5- 31 21,450 23,550 45,000
The Problem 5- 31 approach directly traces 15,000 of general support costs to the individual jobs. In Problem 5- 30, these costs are allocated on the basis of direct professional labor-hours. The averaging assumption implicit in the Problem 5- 30 approach appears incorrectfor example, the St. Edith's Glass job has travel costs six times higher than the Campa Coal case despite having lower direct professional labor-hours.
