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 4,455 1,755 2,980 Total Costs $325,080 208,980 299,070 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 2,240 units of production. X per unit x Total cost for 2,240 units: Feedback
