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 2,210 $152,850 910 98,280 1,620 128,090 a. Determine the variable cost per unit and the total fixed cost, per unit Variable cost: (Round to the nearest dollar.) Total fixed cost: b. Based on part (a), estimate the total cost for 1,120 units of production Total cost for 1.120 units
