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 1,200 2,500 $164,160 201,370 255,360 3,600 a. Determine the variable cost per unit and the total fixed cost. Variable cost: (Round to the nearest dollar.) Total fixed cost per unit b. Based on part (a), estimate the total cost for 1,730 units of production.) Total cost for 1,730 units:
