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 a production are as follows: Units Produced 4,650 1.550 2,910 Total Costs $234,360 150,660 169,410 a. Determine the variable cost per unit and the total fixed cost Variable cost: (Round to the nearest dollar) per unit Total Fed cost: b. Based on part (a), estimate the total cost for 2,230 units of production Total cost for 2,230 units
