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 6,240 $393,120 2,340 252,720 4,550 303,540 a. Determine the variable cost per unit and the total fixed cost. Variable cost (Round to two decimal places.) per unit Total fixed cost b. Based on part (a), estimate the total cost for 3,090 units of production Total cost for 3,090 units:
