High-Low Method Shatner Inc. has decided to use the high-low method 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 6,235 $686,280 665,200 4,090 1,935 441,180 a. Determine the variable cost per unit and the total fixed cost. Variable cost: (Round to the nearest dollar.) per unit Total fixed cost: b. Based on part (a), estimate the total cost for 2,940 units of production. Total cost for 2,940 units: Contribution Margin Harry Company sells 34,000 units at $27 per unit. Variable costs are $17.28 per unit, and fixed costs are $178,500. Determine (a) the contribution margin ratio, (b) the unit contribution margin, and (c) income from operations. a. Contribution margin ratio (Enter as a whole number.) % b. Unit contribution margin (Round to the nearest cent.) per unit c. Income from operations
