Overtime or a second shift for 400 extra motors? The GB540 Unit 4 production cost analysis answers at the margin, with a full cost schedule and a crossover near 4,770 units. Searches like "gb 540 unit 4 assignment example", "gb540 unit 4 sample" and "gb540 unit 4 example" land here.
What a finished GB540 Unit 4 production cost analysis looks like
About six pages around one schedule and one comparison. The schedule runs from 2,000 to 5,200 motors a year in steps of 400 and gives total cost for each row, its three per-unit averages, and the marginal cost of the last motor added. Fixed cost is $2.9 million a year; variable cost is $2,280 a motor on straight time, of which the battery pack accounts for $1,400. Above 3,200 motors, overtime and rising scrap push marginal cost up, to $2,458 at 3,600 and $2,602 at 4,800. The comparison table sets overtime against a second shift that adds $310,000 of supervision and a $26 night premium per motor: $61,600 against $320,400 at 3,600 motors, with the two meeting near 4,770. A short section on a 3 percent pack discount, worth $42 a motor above 4,000 packs, precedes the recommendation.
How a GB540 Unit 4 example is structured
Cost concepts are defined by their behavior rather than by glossary: fixed cost is what the plant pays at zero output, and marginal cost is what the next motor adds. The schedule is built from a stated cost function, so every row can be reproduced, and the paper works one row's arithmetic in full. Interpretation follows the curves: average fixed cost falls throughout, average variable cost stays flat until overtime begins, and average total cost keeps falling across the whole range because marginal cost never rises above it. That observation matters for the decision, since it means the plant has not yet reached its lowest average cost. The shift comparison is framed as incremental cost only, what each option adds beyond straight time, and solved for the crossover volume. Sunk tooling costs are named and excluded. The recommendation states a trigger volume rather than a permanent answer.
A cost function, stated
Fixed cost of $2.9 million, straight-time variable cost of $2,280 a motor, and an overtime premium that starts at $130 and climbs 12 cents with each further motor. The paper writes these out before building a single row.
Nine rows, 2,000 to 5,200 motors
Total cost rises from $7.46 million to about $15.26 million. Average total cost falls from $3,730 to $2,934, and the paper explains why it never turns upward inside this range of output.
The margin above 3,200
Marginal cost is flat at $2,280 until straight time runs out, then climbs to $2,458 at 3,600 motors and $2,602 at 4,800. Pricing and output choices, the paper argues, should use these figures rather than the average.
Overtime against a second shift
Four hundred extra motors cost $61,600 on overtime and $320,400 on a second shift. The two options meet near 4,770 motors, found by solving the quadratic that the rising overtime premium creates.
A trigger, not a verdict
The recommendation is overtime for next year and a second shift only once firm orders pass about 4,770. The pack discount at 4,000 packs is noted but judged too small to move that trigger.
Where marks go in GB540 Unit 4
Production cost analyses in GB540 commonly confuse average and marginal cost, using the average to decide whether one more unit is worth making, which is the error the unit is built to catch. Schedules copied from a textbook pattern, with no stated cost function behind them, cannot be checked and draw comment. Sunk costs slipping into an incremental comparison, tooling already paid for counted against the second shift, distort the decision in a way graders look for. Stopping at the schedule, with U-shaped curves described in general, forfeits the application row the prompt usually carries. A crossover asserted rather than solved earns less than one with the algebra shown. Recommendations framed as permanent, always use overtime, miss that the answer depends on volume and ought to carry a trigger.

GB540 Unit 4 questions, answered
Why does marginal cost matter more than average cost for this decision?
Because the decision is about additional output. Average cost spreads fixed cost across every unit already made, so it says little about what one more unit adds. If marginal cost is below the price the extra unit earns, making it raises profit, whatever the average shows. Most GB540 prompts in this unit test exactly that distinction in some form.
Should sunk costs appear in a production cost analysis?
They can appear, labeled, but they should not influence the decision. Money already spent on tooling or equipment is gone whichever option the firm chooses. Include only costs that change with the choice: added labor, supervision, scrap and materials. Graders often check this specifically, so name any sunk cost you exclude and say why it stays out.
What if my cost data do not produce U-shaped curves?
Report what the data show. Many real plants operate on the falling portion of average cost, especially with high fixed costs, and a paper that notices this is stronger than one forcing a textbook shape onto the numbers. Explain why average cost behaves as it does, usually by comparing it with marginal cost at each output level.
