eBook Show Me How Calculator Print Item 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 6,400 $492,800 2,400 316,800 4,310 348,130 a. Determine the variable cost per unit and the total fixed cost. Variable cost: (Round to the nearest dollar.) 69.22 X per unit 49,729 X Total fixed cost: $ b. Based on part (a), estimate the total cost for 3,170 units of production Total cost for 3,170 units: $ 269,156. X Check My Work Divide the difference between the highest and lowest total costs by the difference between the highest and lowest production units. Multiply the variable unit cost by the number of units for a month this variable cost from the month's total cost to arrive at the fixed cost. The resulting amount should be the same for either the highest or lowest production month
