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 1,050 2,140 3,150 Total Costs $147.420 214,740 229,320 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 1,510 units of production. per unit Total cost for 1,510 unlts
