High-Low Method Ziegler Inc. has decided to use the high-low method to estimate the total cost and the fixed and variable cost components of the total cost. The data for various levels of production are as follows: Units Produced Total Costs 1,760 $253,440 3,230 375,650 4,960 394,240 a. Determine the variable cost per unit and the total fixed cost. Variable cost: (Round to the nearest dollar.) per unit Total fixed cost: b. Based on part (a), estimate the total cost for 2,420 units of production. Total cost for 2,420 units
