Alden Co.s monthly unit sales and total cost data for its operating activities of the past year follow. Management wants to use these data to predict future fixed and variable costs.

Month	Units Sold					Total Cost				Month		Units Sold					Total Cost
1			320,000			$	160,000			7				340,000				$	220,000
2			160,000				100,000			8				280,000					160,000
3			280,000				220,000			9				80,000					64,000
4			200,000				100,000			10				160,000					140,000
5			300,000				230,000			11				100,000					100,000
6			200,000				120,000			12				110,000					80,000

2 Estimate both the variable costs per unit and the total monthly fixed costs using the high-low method. (Do not round Intermediate calculations.) High-Low method - Calculation of variable cost per unit High-Low -thod - Calculation of fixed costs Total cost at the high point Variable costs at the high point Volume at the high point: Variable cost per unit Total vanable costs at the high point Total Fixed costs Total cost at the low point Variable costs at the low point: Volume at the low point.
