To be profitable, a firm has to recover its costs. These costs include both its fixed and its variable costs. One way that a firm evaluates at what stage it would recover the 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 Petrox Oil Co.: Petrox Oil Co. is considering a project that will have fixed costs of $12,000,000. The product will be sold for $32.50 per unit, and will incur a variable cost of $10.75 per unit. Given Petrox's cost structure, it will have to sell units to break even on this project (QBE) Petrox's marketing and sales director doesn't think that the firm's market is big enough for the firm to will be able to sell only about 150,000 units. However, she also thinks that the demand for Petrox's product is relativelyi increase the sales price without significantly decreasing the volume of product set to break even? nelastic (so the firm can sold). Assuming that the firm can sell 150 ,000 units, what price must it $108.90 per unit $90.75 per unit $86.21 per unit $99.83 per unit What affects the firm's operating break-even point? Several factors affect a firm's operating break-even point. Based on the scenarios described in the following table, indicate whether these factors would increase, decrease, or leave unchanged a firm's break-even quantity-assuming that only the listed factor changes and all other relevant factors remain constant. Increase Decrease No Change The firm's fixed costs increase. The variable cost per unit decreases. The firm's tax rate increases. When a large percentage of a firm's costs are fixed, the firm is said to have adegree of operating leverage
