Metod 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 6,380 $221,760 1.980 142,560 4,350 156,660 a. Determine the variable cost per unit and the total fixed cost Variable costi (Round to the nearest dollar) Total fixed cost: b. Based on port(a), estimate the total cost for 3,010 units of production Total cost for 3,010 units: per unit
