Textbook Question
Chapter 6, Problem 4P
Three mutually exclusive design alternatives are being considered. The estimated sales and cost data for each alternative are given on p. 305. The MARR is 20% per year. Annual revenues are based on the number of units sold and the selling price. Annual expenses are based on fixed and variable costs. Determine which selection is preferable based on AW. State your assumptions. (6.4)

Dupont can purchase a 1-year option for $100,000 that will provide time to pilot test the LLD process or Dupont can acquire the license now at a cost of $1.8 million plus 25% of sales paid annually to the license owner. If they wait 1 year, the cost will increase to $1.9 million plus 30% of sales paid annually. If sales are estimated to be $1,000,000 per year over the 5-year license period, should Dupont purchase the license now or purchase the option now and possibly license it after the 1-year test period?

- AE Criterion - Single Project* *Blank & Tarquin (2005). Engineering Economy, 7th edition. Example 6.3. The owner of a pizza shop plans to purchase and install five portable in-car systems to increase delivery speed and accuracy. Each system costs $4600, has a 5-year useful life, and may be salvaged for an estimated $300. Total operating cost for all systems is $1000 for the first year, increasing by $100 per year thereafter. The owner estimates increased net income of $6000 per year for all five systems. Is this project financially viable at an MARR of 10%?arrow_forwardTony works for ABC Window Products.
