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 910 $156,240 1,670 183,670 2,310 243,040 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 1,160 units of production. Total cost for 1,160 units
