Cost-volume-profit [CVP] analysis is a widely-used, basic business model. Discuss the underlying assumptions made in the application of the model and whether or not these limit the usefulness of the model. Would you rely on the model

Cost-volume-profit [CVP] Analysis

The cost-volume-profit analysis model assumes that the total fixed cost, the variable cost per unit, and the selling price per unit remain constant within the relevant range.

It is very difficult for a company to remain in the relevant range, where the assumptions will be obtained.  Market forces, including the dynamics of competition change the underlying assumptions.  For example, a company may become more efficient in its operations, thereby reducing its variable cost per unit.  The total fixed cost may also change when the company increases its activity levels.

However, these limitations do not make the model less useful.  It can be relied on to make short-run profit and pricing decisions.

Explanation:

The management of a business finds the CVP model useful in making important management decisions, especially decisions that relate to budgeting of production and sales, cost control, and profit planning.  Management uses the CVP model to determine the break-even point in both units and sales dollars.  Overall, management relies on the model to select its competitive products.

ans.

heterothermic organisms include those organisms that can switch between homeothermic (having body temperature higher than environment) and poikilothermic (having variation in internal body temperature) strategies.

some migratory birds show heterothermy as they decrease their metabolic rate during cold nights to keep their body temperature low. drop in metabolic rate allows increase in production efficiency of birds that reduces the internal body temperature to make it equal to external cold temperature during cold nights.

thus, the correct answer is 'birds allow their temperature drop in order to increase their production efficiency.'
