Set #1 - CVP Deadline: November 26‚ 2011 A. The break-even point in units can be computed as Fixed Costs divided by the contribution margin per unit. On the other hand‚ the break-even point in pesos can be computed as Fixed Costs divided by the contribution margin ratio. Using the profit equation π = TR – TC; where π = operating profit‚ TR = Total Revenue and TC = Total Cost‚ derive the break-even formulas. B. From the profit equation π = TR – TC‚ derive the formula for the following: 1
