Which of the following is true of a variable cost? O A variable cost decreases on a per unit basis as output decreases and increases on a per unit basis as output increases O A variable cost increases in total as output decreases and decreases in total as output increases O A variable cost decreases on a per unit basis as output increases and increases on a per unit basis as output decreases O A variable cost remains constant or is fixed on a per unit basis within the relevant range O None of the above ADBE Inc. currently produces 42,150 units of its single product each month. ADBE's relevant range of production is 29,500 units to 59,000 units per month. The company incurs the following unit costs at the current production volume: Direct materials $13.15 per unit Direct labor $20.00 per unit Variable manufacturing $8.55 per unit overhead Fixed manufacturing $12.30 per unit overhead Sales commissions $3.25 per unit Variable administrative $1.55 per unit expense The company is currently considering decreasing its monthly production volume to 39,500 units. What would be the total manufacturing cost associated with the new production volume of 39,500 units per month? Which of the following statements about the method of least squares (regression) is FALSE? O Is a way to find the best-fitting line through a set of data points Always produces the same cost formula when used on the same data set O is a statistical way of separating a mixed cost into fixed and variable components O Includes measures of the statistical significance of the relation between the cost driver and the total mixed cost as well as the accuracy of the cost function itself O None of the above (i.e., all of the above statements are true) GME Inc. uses the high-low method to estimate total labor cost, which is a mixed cost. Data for the most recently completed period are provided below: Machine hours Labor costs Highest observation of cost driver 400 $20,000 Lowest observation of 240 $13,600 cost driver What is estimated total labor cost for the coming period if the firm expects to use 300 machine hours in the coming period
