High-Low Method Ziegler Inc. has decided to use the high-low method to estimate the total cost and the fuced and variable cost components of the total cost. The data for various levels of production are as follows Units Produced Total Costs 3.520 $320,320 205.920 2.320 305,220 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 1.740 units of production Total cost for 1.740 O
