Quiz – Chapter 17 – Solution 1. Rider Company sells a single product. The product has a selling price of $40 per unit and variable expenses of $15 per unit. The company’s fixed expenses total $30‚000 per year. The company’s break-even point in terms of total dollar sales is: A) $100‚000. B) $80‚000. C) $60‚000. D) $48‚000. The answer is d. CMR = (P-V)/P = ($40 - $15)/$40 = 62.5% Px = F/ (CMR) Px = $30‚000/.625 = $48‚000 Use the following to answer questions 2-3: Weiss Corporation produces two models

Association: linkage among variables b. Positive Association: values of two different variables increase simultaneously c. Negative Association: inverse; one variable’s value increases as the other decreases d. Non-linear Association: curvilinear; un-proportional increases/decreases between two variables e. Dose-response Relationship: correlative association between an exposure and effect 2. A non-causal association is when one variable is related to but doesn’t cause the other variable (outcome); it is secondary
