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 4,950 $425,040 1,650 273,240 3,230 321,210 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 2,380 units of production. Total cost for 2,380 units: $
