Georgia uses the high-low method of estimating costs. Georgia had total costs of $50,000 at its lowest level of activity, when 5,000 units were sold. When, at its highest level of activity, sales equaled 10,000 units, total costs were $78,000. Georgia would estimate variable cost per unit as: Multiple Choice $14.00 o $9.10 $5.60 o $10.54 The contribution margin ratio is: Multiple Choice the difference between sales revenue and variable costs. the difference between variable costs and fixed costs. variable costs divided by fixed costs. contribution margin per unit divided by sales price per unit. Cost behavior is: Multiple Choice the way in which costs change when the activity level changes. the difference between sales revenue and fixed costs. the same as absorption costing. the amount of sales necessary to achieve a specific profit
