2,500,000
Work Step by Step
Total amount of common fixed expenses = Common fixed expenses * Capacity of each product per unit
Total amount of common fixed expenses for the Alpha product line= 15 * 100,000 = 1,500,000
Total amount of common fixed expenses for the Beta product line= 10 * 100,000 = 1,000,000
The company’s total amount of common fixed expenses = Total amount of common fixed expenses for the Alpha product line + Total amount of common fixed expenses for the Beta product line = 1,500,000 + 1,000,000 = 2,500,000
