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 2,945 $186,200 1,045 1,800 119,700 134,600 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 1,440 units of production. Total cost for 1,440 units: 118378.4 X 45.06 X per unit 53,492 X
