Question 457186
Fixed Cost = Gross Profit - Taxable Income

Where: 
Gross Taxable Income = 40,000/0.6 = 66,666.67
and 
Gross Profit         = Sales * Gross Profit Margin
                     = 400,000 * (12/20)
                     = 240,000

A. Fixed Cost = 240,000 - 66,666.67
              =  173,333.33

Break-even point
Gross Profit = Fixed Cost

Let y = the firm's break-even point in units
  20y = the firm's break-even point in dollars

Gross Profit = y * profit per unit
             = y(20-8)
             = 12y

12y = 173,333.33
  y = 14,445
20y = 288,900

B. The firm's break-even point is 14,445 kegs, $288,900 in dollar sales
