The order of a differential equation is the highest order of any derivative of the unknown function that appears in the equation. Moving left to right, note that the slope is negative, goes through zero at
the turning point, then becomes positive. These two conditions are characteristic
of a function with a minimum point. Note that a negative second derivative means that the first derivative is always
decreasing for a given (positive) change in x, i.e., as x increases, (always
reading the graph from left to right). Recall
that second derivatives give information about the change of slope. We
can use that in conjunction with the first derivative at increasing points of
x (as you travel left to right on the graph) to determine identifying characteristics
That is, all variable costs are differential costs for the two alternatives facing the Company. Allocated fixed costs—fixed costs that cannot be traced directly to a product—are typically not differential costs. No, differential cost analysis does not take sunk costs into account. Sunk costs are expenses already incurred, and the present decision cannot change.
However, management may want a more concise explanation of why profit is $10,000 higher when all three product lines are maintained. Discontinuing a product to avoid the losses and increase profits – decision to drop a product line. It is a useful tool for making strategic decisions in various business contexts. Its numerous uses are essential for maximizing revenue, allocating resources efficiently, and attaining strategic objectives. Deciding how much to charge for goods or services is an essential choice for any organization.
- Management must compare the price paid for a part with the additional costs incurred to manufacture the part.
- And panel C presents the differential analysis for the two alternatives.

- The $4,000 is the income that ABC would forego for remaining with the old marketing techniques and failing to adopt the more sophisticated marketing models.
The cost information provided by activity-based costing is generally regarded as more accurate than most traditional costing methods. Differential analysis provides a format for these types of decisions. The general rule is to select the alternative with the highest differential profit. (i) To process the entire quantity of ‘utility’ so as to convert it into 600 numbers of ‘Ace’. The concern at present produces per day 600 numbers of each of the two products for which 2,500 labour hours are utilised.
To illustrate, assume that the Campus Bookstore is considering eliminating its art supplies department. If the bookstore dropped the art supplies department, it would lose revenues of $100,000 annually. The bookstore’s management assigns costs of $110,000 ($80,000 variable and $30,000 fixed) to the art supplies department. Therefore, art supplies has an apparent annual loss of $10,000 ($100,000 revenue minus $110,000 costs). These fixed costs would continue to be incurred and would not be saved by closing the art supplies department.
A baseball is thrown upward from a height of \(3\) meters above Earth’s surface with an initial velocity of \(10\) m/s, and the only force acting on it is gravity. Of course, this is not realistic, and as our models become more realistic in
the multivariate section, we will add constraints
to our optimization problems. Note that we were able to prove average cost is minimized when Q is 12, without
having to actually determine the average cost. Recall from past section on linear
functions that the slope of a horizontal line or function is equal to

In the given problem, the company should set the level of production at 1,50,000 units because after this level differential costs exceed the incremental revenue. While variable costs fluctuate in direct proportion to production or activity levels, fixed costs are constant regardless of the degree of production. Knowing the difference between the two makes determining which expenses apply to a certain decision easier. Differential cash flows refer to the net change in cash flows between two alternatives. Differential contribution margin is the net change in contribution margin between two choices.

External costs are costs imposed on third parties or society as a whole, which are not accounted for by the business itself. These costs can include pollution, but they are not directly incurred by the business as a differential cost formula result of its decisions. Differential costs, sometimes called incremental, are the overall costs incurred while choosing between several options. Direct material and labour will be constant for the special order.
Suppose the function
is a higher order polynomial, one that takes the shape of a curve with 2 or
more turning points. It would be easy to imagine a function where part
was below the horizontal tangent line, turned again, and came back up past the
line. The definition of concavity refers only to the part of the function
near the point where the tangent line touches the curve, it isn’t required to
hold https://adprun.net/ everywhere on the curve. A very clear way to see how calculus helps us interpret economic information
and relationships is to compare total, average, and marginal functions. Although using quantitative factors for decision making is important, management must also consider qualitative factors. Using these quantitative factors to make decisions allows managers to support decisions with measurable data.
Any price above this minimum selling price represents incremental profit for the company. The company then calculates the estimated revenue by multiplying the expected output at a specific level by the selling price. Companies use this same form of differential analysis to decide whether they should discard their by-products or process them further. By-products are additional products resulting from the production of a main product and generally have a small market value compared to the main product. For example, the bark from trees cut into lumber is a by-product of lumber production. Although a by-product, companies convert this bark into fuel or landscaping material.
Therefore the baseball is \(3.4\) meters above Earth’s surface after \(2\) seconds. It is worth noting that the mass of the ball cancelled out completely in the process of solving the problem. Evaluate the second derivative at Q equals 24 to determine concavity.
Conversely, if incremental cost leads to a decrease in product cost per unit, a company can choose to reduce product price and increase profit by selling more units. However, sales revenue, variable costs, and fixed costs are traced directly to customers rather than to product lines. Differential costs are the increase or decrease in total costs that result from producing additional or fewer units or from the adoption of an alternative course of action. In the above analysis, it is ascertained that the fixed overheads and a portion of semi-variable overheads remain constant for both the alternatives.
