Relevant cash flows for a marketing campaign Marcus Tube, a manufacturer of high-quality aluminum tubing, has maintained stable sales and profits over the past 10 years. Although the market for aluminum tubing has been expanding by 3% per year, Marcus has been unsuccessful in sharing this growth. To increase its sales, the firm is considering an aggressive marketing campaign that centers on regularly run- ning ads in all relevant trade journals and web sites and exhibiting products at all major regional and national trade shows. The campaign is expected to require an annual tax-deductible expenditure of S150,000 over the next 5 years. Sales revenue, as shown in the accompanying income statement for 2015, totaled S20,000,000. If the proposed marketing campaign is not initiated, sales are expected to remain at this level in each of the next 5 years, 2016 through 2020.
