Activity Examination, Cost Patterns, and Price Estimation
ANSWERS TO REVIEW QUERIES
7-1Cost tendencies patterns are crucial in the process of making cost predictions. Cost forecasts are used in planning, control, and making decisions. For example , expense budgets derive from predictions of costs for various degrees of activity. Expense control can be accomplished by evaluating actual costs against budgeted costs, that are based on price predictions. Cost predictions can also be important in decision making, considering that the desirability of varied alternatives generally depends on the costs that will be received under these alternatives.
7-2a. Cost appraisal is the technique of determining what sort of particular price behaves.
m. Cost actions are the relationship among cost and activity.
c. Cost conjecture is the forecast of price at a particular level of activity.
Cost appraisal determines the price behavior routine, which is used to produce a cost prediction about the charge at a specific level of activity contemplated later on.
7-3a. Motel: Percentage of rooms filled or the volume of occupancy-days, exactly where an occupancy-day is defined as a single room entertained for one day.
b. Medical center: Patient-days, in which a patient-day is defined as a one-day stay by one individual.
c. Computer manufacturer: Number of computers manufactured, throughput, architectural specifications, architectural change instructions, or quantity of parts in the finished item.
d. Computer system sales retail store: Sales revenue.
e. Pc repair service: Repair phone calls or hours of fix service.
n. Public accounting firm: Hours of auditing service provided by each classification of staff (partner, director, supervisor, elderly accountant, and staff accountant).
4. Charts of the cost tendencies patterns are as follows:
7-5As the level of activity (or expense driver) raises, total fixed cost remains to be constant. Nevertheless , the set cost per unit of activity diminishes as activity increases.
7-6A manufacturer's cost of supervising creation might be a step-fixed expense, because one particular supervisor is required for each shift. Each move can allow for a certain selection of production activity; when activity exceeds that range, a new shift must be added. When the new shift is definitely added, a brand new production director must be employed. This new placement results in a jump in the step-fixed cost to a higher level.
7. Because the level of activity (or price driver) boosts, total changing cost improves proportionately plus the variable expense per product remains constant.
8. a. A semivariable cost habit pattern may be used to approximate a step-variable price as displayed in the subsequent graph:
7-9(a)Annual cost of preserving an interstate highway: committed cost. (Once the motorway has been constructed, it must be managed. The travel authorities will be largely committed to spending the necessary funds to take care of the highway adequately. )
(b)Ingredients within a breakfast food: engineered expense.
(c)Advertising for the credit card business: discretionary price.
(d)Depreciation with an insurance company's computer: determined cost.
(e)Charitable donations: discretionary cost.
(f)Research and expansion: discretionary expense.
7-10The cost analyst should respond by pointing out that in many instances a cost habit pattern must be limited to the relevant range of activity. When the business utility cost was demonstrated as a semivariable cost, it is likely that only several portion during the chart would fall within the relevant range. In the relevant selection, the business's utility price can be approximated reasonably tightly by a semivariable cost habit pattern. Nevertheless , outside that range (including an activity standard of zero), the semivariable expense behavior pattern should not be employed as an...
