The difference in cost divided by the difference in activity is the variable rate. Once the variable rate is found, the fixed portion is determinable. The high-low method is a simple approximation of the mixed cost formula. The costs of using more sophisticated methods sometimes outweigh the incremental accuracy achieved. In these cases, the high-low method is sufficient 2 / 10 Lar Company has found that its total electricity cost has both a fixed component and a variable component within the relevant range. The variable component seems to vary directly with the number of units produced. Which one of the following statements concerning Lar‟s electricity cost isincorrect? The variable electricity cost per unit of production will remain constant as production volume increases The fixed electricity cost per unit of production will decline as production volume increases The total electricity cost per unit of production will increase as production volume increases The total electricity cost will increase as production volume increases Because of the fixed portion, the per-unit cost of a mixed, or semivariable, cost will decrease as production volume increases 3 / 10 Which one of the following is correct regarding a relevant range ? Total fixed costs will not change Total variable costs will not change Actual fixed costs usually fall outside the relevant range The relevant range cannot be changed after being established The relevant range is the range of activity over which unit variable costs and total fixed costs are constant. The incremental cost of one additional unit of production will be equal to the variable cost 4 / 10 Which one of the following categories of cost is most likelynotconsidered a component of fixed factory overhead ? Depreciation Property taxes Rent Power A fixed cost is one that remains unchanged within the relevant range for a given period despite fluctuations in activity. Such items as rent, property taxes, depreciation, and supervisory salaries are normally fixed costs because they do not vary with changes in production. Power costs, however, are at least partially variable because they increase as usage increases 5 / 10 The relevant range refers to the activity levels over which : Relevant costs are incurred Production varies Costs fluctuate Cost relationships hold constant The relevant range defines the limits within which per-unit variable costs remain constant and fixed costs are not changeable. It is synonymous with the short run. The relevant range is established by the efficiency of a company‟s current manufacturing plant, its agreements with labor unions and suppliers, etc 6 / 10 Which one of the following refers to a cost that remains the same as the volume of activity decreases within the relevant range ? Variable cost per unit Total variable cost Unit fixed cost Average cost per unit Variable cost per unit remains constant in the short run regardless of the level of production. This is in contrast with variable costs in total, which vary directly and proportionally with changes in volume 7 / 10 When identifying fixed and variable costs, which one of the following is a typical assumption concerning cost behavior ? General and administrative costs are assumed to be variable costs The relevant time period is assumed to be 5 years Cost behavior is assumed to be realistic for all levels of activity from zero to maximum capacity Total costs are assumed to be linear when plotted on a graph Total costs, being a mixture of fixed and variable costs, are assumed to be linear 8 / 10 The sum of the costs necessary to effect a one-unit increase in the activity level is a(n) : Opportunity cost Marginal cost Incremental cost Differential cost A marginal cost is the sum of the costs necessary to effect a one-unit increase in the activity level. Differential (or incremental) cost is the difference in total cost between two decisions. Opportunity cost is the maximum benefit forgone by using a scarce resource for a given purpose. It is the benefit, for example, the contribution to income, provided by the best alternative use of that resource. 9 / 10 Cell Company has discovered that the cost of processing customer invoices is strictly variable within the relevant range. Which one of the following statements concerning the cost of processing customer invoices isincorrect? The cost of processing the 100th customer invoice will be the same as the cost of processing the first customer invoice The total cost of processing customer invoices will increase as the volume of customer invoices increases The cost per unit for processing customer invoices will decline as the volume of customer invoices increases The average cost per unit for processing a customer invoice will equal the incremental cost of processing one more customer invoice Variable cost per unit remains constant in the short run regardless of the level of production (The total cost of processing customer invoices will increase as the volume of customer invoices increases) incorrect :Since the cost in question is strictly variable within the relevant range, the total cost will increase as the volume increases. (The cost of processing the 100th customer invoice will be the same as the cost of processing the first customer invoice) incorrect : Since the cost in question is strictly variable within the relevant range, the unit cost remains the same. (The average cost per unit for processing a customer invoice will equal the incremental cost of processing one more customer invoice) incorrect : Since the cost in question is strictly variable within the relevant range, the average cost per unit is the same as the incremental cost. 10 / 10 Which of the following is thebestexample of a variable cost ? Cost of raw material Interest charges Property taxes The corporate president’s salary Variable costs vary directly with the level of production. As production increases or decreases, material cost increases or decreases, usually in a direct relationship Your score is LinkedIn Facebook Twitter VKontakte 0% Send feedback 🚀 Join Telegram Group 📢 Telegram Channel 📘 Facebook Group 👍 Facebook Page 📌 Pinterest
