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: a. Determine the variabie cost per unit and the total fixed cost, Variable cost (Round to two decimal places.) per unit Total fixed cost 1 per unit: b. Based on part (a), estimate the total cost for 115,000 units of production. Total cost for 115,000 units \&
