To be profitable, a firm has recover its costs. These costs include both fixed and variable costs. One way that a firm evaluates at what stage it would recover its invested costs is to calculate how many units or how much in dollar sales is necessary for the firm to earn a profit. Consider the case of Defense Dynamics: Defense Dynamics Inc. is considering a project that will result in fixed costs of $12,000,000 and per-unit variable costs of $10.75....
