Q1:  Problem 6.1 and the chapter-ending practice problem accompanying it discuss Differential Cost Analysis.  Read through these examples and understand (without concentrating on the math) what these examples are telling us.  What is the overall concept of this and why is it done (how does it benefit managers)?

Q2:  Problem 6.2 and the chapter-ending practice problem accompanying it discuss Job Order Costing.  Read through these examples and understand (without concentrating on the math) what these examples are telling us.  What is the overall concept of this and why is it done (how does it benefit managers)?

Q3:  Problem 6.3 and the chapter-ending practice problem accompanying it discuss Activity-Based Costing.  Read through these examples and understand (without concentrating on the math) what these examples are telling us.  What is the overall concept of this and why is it done (how does it benefit managers)?

Q4:  Problem 6.4 and the chapter-ending practice problem accompanying it discuss Break-Even Analysis.  Read through these examples and understand (without concentrating on the math) what these examples are telling us.  What is the overall concept of this and why is it done (how does it benefit managers)?
