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 1,495 2,380 Total Costs $149,040 179,010 per unit 3,795 231,840 a. Determine the variable cost per unit and the total fixed cost. Variable cost: (Round to the nearest dollar.) Total fixed cost: b. Based on part (a), estimate the total cost for 1,900 units of production. Total cost for 1,900 units
