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 1,035 $219,420 2,320 224,300 3,335 341,320 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 1,570 units of production Total cost for 1,570 units
