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 80,000 $25,100,000 27,206,000 92,000 120,000 32,120,000 a. Determine the variable cost per unit and the total fixed cost. per unit Variable cost (Round to two decimal places.) Total fixed cost b. Based on part (a), estimate the total cost for 115,000 units of production. Total cost for 115,000 units
