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 800 $187,200 1,600 191,360 2,400 291,200 a. Determine the variable cost per unit and the total fixed cost. per unit Variable cost: (Round to the nearest dollar) Total fixed cost b. Based on part (a), estimate the total cost for 1,150 units of production Total cost for 1,150 units
