Some Deviations in Answers Your independent solutions to fuhdamentos text problems may yield answers slightly different from mine due to rounding differences. In some cases, the interpretations and assumptions students bring to the problems may differ from my own in creating them, again resulting in different answers.

Some of the answers not the procedures to the end-of-chapter problems are posted in the book’s companion website, so that students can check the answers on their own. Having made these disclaimers, I wish to emphasize that it is my and the publisher’s intention to provide the most accurate solutions possible.

Thus, if you discover any typo errors, or disagree strongly with the interpretation and assumptions required of a particular solution, please do not hesitate to report your concerns to me via email at park eng. I will also plan on posting any errors on the book’s web site under “Instructor Resource Center.

Chapter 1 Engineering Economic Decisions There fundamwntos no end-of-chapter questions in this introductory chapter. However, the following questions could be added as a part of instruction: Ask students to review the contents of The Wall Street Journal for the past 3 months.

Then, identify and categorize the types of investment decisions appeared in the journal according to the types of strategic economics decisions discussed in the text. Work in small groups and brainstorm ideas about how a common appliance, device or tool could be redesigned to improve it in some way. Identify the steps involved and the economic factors, which you would need to consider prior to making a decision to manufacture the 5ga product.

A detailed design and actual cost estimates are not required. Some items, which could be considered for this redesign exercise, are: What is the price of today? Why 5tx these prices so difficult to predict? Imagine what the consequences would be if you used these optimistic estimates in your economic analysis in your early project undertaking. What would be some practical ways to consider this type of variation in economic analysis?

Time Value of Money 2. Therefore, the annual revenue can be expressed as follows: Chapter 3 Understanding Money Management 3. Referring A to his quarterly deposit amount, we obtain the following: We first need to find the effective interest rate per payment period month30 days per month: First, find the remaining balance at the end of 60 months: With equal balances, all will pay the same interest. To find the effective interest rate for this new transaction, we set up the following equivalence relationship and solve for i: However, reasoning this line neglects the time value of money for the portion of principal payments.

This is done by calculating the equivalent future worth of the loan payment series. With Excel, you may enter the loan payment series and use the IRR range, guess function to find the effective interest rate.

Conventional mortgage using either Excel or Loan Analysis Program at the books websitehttp: Chapter 4 Equivalence Calculations under Inflation 4. If you use the Rule of 72, you may find 72 Since the annuity payments are made in actual dollars, we use the market interest rate to find its equivalent lump sum amount in todays dollars. As an alternative way of finding the equivalent cash flows in actual dollars, we may use the compound growth rate geometric growth and inflation: The 16th interest payment 8th year in constant dollars: Since the first withdrawal is made after 6 months from retirement, it is necessary to calculate the effective inflation rate per half-year.

On a semiannual basis, the first withdrawal will be made after 41 semiannual periods. Then, we can calculate the equivalent amount of this first withdrawal in actual dollars as follows: To find the required equal monthly deposit amount Awe establish the following equivalence relationship: As shown in the following table, it will cost almost eight 7.

Municipal bond is a clear choice for any value of MARR. In this case, it fundamenttos be easier to use the constant dollar analysis, as we dont need to project the future price increase of the subscription, assuming that the price of magazine will follow the general inflation rate.

Then, we need to determine which interest rate to use in evaluating the three different subscription options. Certainly the choice will change depending upon the individual decision-makers true earrings requirement.

Chapter 5 Present-Worth Analysis 5. The cost of building is given as if Cmax is being built from scratch. No credit is given for the capacity already in place.

Power bill is paid at years end, not monthly. Motor B is preferred. Purchase Model A now and repeat Model A forever. Purchase Model B now and replace it at the end of year 2 by Model A.

Then repeat Model A forever. Process device A lasts only 4 years. You have a required service period of 6 years. If you take this option, you must consider how you will satisfy the rest of the required service period at the end of the project life. This option creates no problem because its service life coincides with the required service period. Chapter 6 Annual Equivalence Method 6.
