C723 Quantitative Analysis for Business at Western Governors University teaches formal decision-making models that turn business data into better choices, from expected value to linear programming.
WGU's B.S. Accounting program guide lists the course at three competency units in term four, with no prerequisites. The guide names expected value, linear programming and inventory models, project scheduling with the critical path method, measures of uncertainty, crash costs and spreadsheet-based graphs.
Students who are comfortable with basic algebra usually manage the formulas. The harder part is choosing the right model for a word problem and explaining what the answer means for the business.

What C723 Covers
The program guide lists five competencies:
| Competency (summarized) | What it means |
|---|---|
| Describe business purposes for quantitative methods | Knowing which model suits which decision |
| Analyze data numerically and graphically | Summary measures, charts and spread |
| Use expected value for decisions | Weighing outcomes by probability |
| Analyze projects with the critical path | Scheduling and controlling project cost |
| Use linear programming, EOQ and graphs | Optimizing under constraints and ordering stock |
Key Concepts Explained
Expected Value
Expected value multiplies each outcome by its probability and adds the results. It tells you the average result if the decision were repeated many times.
Example: A product launch has a 60% chance of earning $80,000 and a 40% chance of losing $20,000. Expected value = (0.6 x 80,000) + (0.4 x -20,000) = 48,000 - 8,000 = $40,000. If the alternative is a safe project earning $35,000, the launch has the higher expected value, though it carries more risk.
Economic Order Quantity
EOQ balances ordering costs against holding costs. The formula is EOQ = √(2DS / H), where D is annual demand, S is the cost per order and H is the annual holding cost per unit.
Example: D = 12,000 units, S = $50 and H = $3. EOQ = √(2 x 12,000 x 50 / 3) = √400,000 ≈ 632 units per order.
Linear Programming
Linear programming finds the best value of an objective, such as maximum profit, subject to constraints such as labor hours or materials. With two products, you can graph the constraints, find the corners of the feasible region and test each corner in the objective function. Spreadsheet solvers do the same for larger problems.
Critical Path and Crashing
The critical path is the longest path through a project network. Crashing shortens it by spending extra money on critical activities; you crash the activity with the lowest cost per day saved first, and stop when another path becomes critical or the cost outweighs the benefit.
Typical Assignments and How to Approach Them
WGU assesses competency through performance assessments or objective assessments; check your course page for the current format. Work in this subject usually involves:
| Task type | What it tests | How to approach it |
|---|---|---|
| Decision under uncertainty | Expected value | Build a payoff table first |
| Product mix problem | Linear programming | Define variables, objective, constraints |
| Inventory question | EOQ and reorder logic | Check units: annual vs per order |
| Project schedule | Critical path and crashing | Draw the network before calculating |
Building Models in a Spreadsheet
The course description mentions electronic spreadsheets and graphs, and most of these models are easier and safer in Excel. Good habits make errors visible:
- Put inputs (probabilities, costs, demand) in labeled cells and refer to them in formulas.
- Never type a result over a formula; it hides mistakes.
- Use Solver for linear programming and check that the constraints are entered with the right signs.
- Add a chart where it helps, for example the feasible region or total cost against order quantity.
- Write one sentence under each output explaining the business decision it supports.
Where Students Get Stuck
- Choosing the wrong model. Ask what is being decided: a choice under risk (expected value), a best mix (linear programming), an order size (EOQ) or a schedule (critical path).
- Unit mismatches. Annual demand with monthly holding costs gives a wrong EOQ.
- Constraint errors. A "less than or equal to" entered the wrong way changes the answer completely.
- No interpretation. A number alone rarely answers the question; say what the manager should do.
Study Tips for C723
- Keep a formula sheet with one worked example per model.
- Rewrite each word problem as a list of knowns and unknowns before calculating.
- Check answers for common sense: a negative order quantity or a 300% probability means an error.
- Practice crashing problems slowly; they reward careful, step-by-step working.

Frequently Asked Questions
WGU's B.S. Accounting program guide lists Quantitative Analysis for Business at three competency units, in term four.
The program guide says the course has no prerequisites, though comfort with basic algebra helps.
EOQ = √(2DS / H), where D is annual demand, S is the ordering cost per order and H is the annual holding cost per unit.
Crashing shortens a project by adding resources to critical path activities, starting with the cheapest cost per day saved.
The course description refers to spreadsheets and graphs, and Excel Solver is the usual tool for linear programming problems.
