High-Low Method Tashiro 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 4,480 $313,600 1,680 201,600 2,960 293,660 a. Determine the variable cost per unit and the total fixed cost. Variable cost (Round to two decimal places.) $fill in the blank 1 per unit Total fixed cost $fill in the blank 2 b. Based on part (a), estimate the total cost for 2,220 units of production. Total cost for 2,220 units: $fill in the blank 3
