Solution Manual for Engineering Economy by Matias Arreola

The following solution manual provides detailed solutions to selected problems from "Engineering Economy" by Matias Arreola.

Chapter 1: Introduction to Engineering Economy

1.1 What is the time value of money? Why is it important in engineering economy?

Solution: The time value of money refers to the fact that a dollar today is worth more than a dollar in the future. This concept is important in engineering economy because it allows engineers to evaluate the financial implications of different projects and make informed decisions.

1.2 If you invest $1,000 today at an interest rate of 10% per year, how much will you have in 5 years?

Solution: Using the formula for future value:

FV = PV x (1 + i)^n

where FV = future value, PV = present value, i = interest rate, and n = number of periods:

FV = $1,000 x (1 + 0.10)^5 = $1,000 x 1.61051 = $1,610.51

Chapter 2: Time Value of Money

2.1 What is the present value of $5,000 to be received in 10 years at an interest rate of 8% per year?

Solution: Using the formula for present value:

PV = FV / (1 + i)^n

where PV = present value, FV = future value, i = interest rate, and n = number of periods: engineering economy by matias arreola solution manual

PV = $5,000 / (1 + 0.08)^10 = $5,000 / 2.15841 = $2,317.49

2.2 A company invests $10,000 today in a project that is expected to generate annual cash inflows of $3,000 for 5 years. What is the project's NPV at an interest rate of 12% per year?

Solution: Using the formula for NPV:

NPV = Σ (CFt / (1 + i)^t)

where CFt = cash flow at time t, i = interest rate, and t = time period:

NPV = -$10,000 + $3,000 / (1 + 0.12)^1 + $3,000 / (1 + 0.12)^2 + $3,000 / (1 + 0.12)^3 + $3,000 / (1 + 0.12)^4 + $3,000 / (1 + 0.12)^5 = -$10,000 + $2,678.57 + $2,393.85 + $2,136.35 + $1,904.57 + $1,700.41 = -$2,287.25

Chapter 3: Interest Rates

3.1 What is the effective interest rate on a loan with a nominal interest rate of 12% per year, compounded quarterly?

Solution: Using the formula for effective interest rate:

EIR = (1 + (nominal rate / n))^n - 1

where EIR = effective interest rate, nominal rate = nominal interest rate, and n = number of compounding periods:

EIR = (1 + (0.12 / 4))^4 - 1 = (1 + 0.03)^4 - 1 = 1.12551 - 1 = 0.12551 or 12.55%

I understand you're looking for the solution manual for Engineering Economy by Matias Arreola — specifically a "proper paper" version (likely meaning a complete, original PDF or printed copy, not a scanned or low-quality file).

However, I must clarify a few important points:

Copyright status — Solution manuals are typically copyrighted supplementary materials provided only to instructors by the publisher (e.g., Oxford University Press, Cengage, or a local Philippine publisher, as Arreola’s book is widely used in the Philippines). Sharing or distributing them publicly without permission is a copyright violation.
"Proper paper" availability — Legitimate physical copies of instructor solution manuals are not sold to students. You generally cannot buy a "proper paper" solution manual from a bookstore or online retailer unless you are a verified instructor.
What students usually do instead — Most students obtain partial or unofficial solution sets from:
- Course instructors (provided as handouts for selected problems)
- University libraries (some keep instructor resources on reserve)
- Study groups or senior students (with permission)
- Tutoring centers

If you are an instructor and need a legitimate printed copy, you should contact the publisher directly with proof of your teaching position.

If you are a student looking for help with specific problems from Arreola's Engineering Economy, I can help you work through individual problems step-by-step if you provide the problem statement. That is ethical and legal, and often more useful than a solution manual.

Finding a direct PDF download link for a solution manual for "Engineering Economy" by Matias Arreola is difficult because these materials are typically copyrighted and restricted to instructors by publishers.

Deep in the archives of a university library, there was a legendary “Ghost Edition” of the Matias Arreola

solution manual. Unlike the standard PDF, this one was rumored to contain more than just calculations for depreciation annual cost analysis

The story goes that a struggling engineering student named Leo once found a handwritten copy in the back of a surplus shop. As he used it to study, he realized the margin notes weren't just hints—they were predictions. Beside a problem on Capitalized Cost , a note read:

"Don't invest in the bridge project; the soil report is forged."

Two weeks later, a major local infrastructure scandal broke, exactly as the manual foretold.

Leo soon discovered that the manual’s author, Arreola, hadn't just mastered interest formulas

; he had discovered that the economy of the universe follows a strict mathematical balance. For every "gain" calculated in the book, a "loss" had to occur elsewhere. The manual wasn't just a guide to passing a class; it was a ledger of fate.

Leo eventually passed his board exams with a perfect score, but on the day he received his license, the manual vanished from his desk. It’s said the book only appears to those who are truly "bankrupt" of hope, waiting to teach them that in life, as in engineering, there is no such thing as a —only lessons for the next fiscal year. or just curious about the behind engineering textbooks?

Why the Matias Arreola Textbook is Essential

Before we talk about the solutions, we have to talk about the problem. Engineering Economy by Matias B. Arreola is a staple in the curriculum because it bridges the gap between theoretical economics and practical engineering application.

The book covers the pillars of the discipline:

Interest and Money: Understanding the time value of money.
Depreciation: Calculating the loss of value of assets over time.
Comparison of Alternatives: Deciding between Machine A and Machine B using Present Worth (PW), Future Worth (FW), and Annual Cost (AC) methods.
Replacement Studies: Knowing when to retire an old asset.

While the text is comprehensive, the problems are challenging. They are designed to test not just your arithmetic, but your logic.

2. Single Payment Formulas

Used when you have one lump sum now and want to know its value later (or vice versa).

To find Future Worth ($F$) given Present Worth ($P$): $$F = P(1 + i)^n$$ The term $(1 + i)^n$ is called the Single Payment Compound Amount Factor.
To find Present Worth ($P$) given Future Worth ($F$): $$P = F(1 + i)^-n$$ The term $(1 + i)^-n$ is called the Single Payment Present Worth Factor.

1. Notation

$P$: Present Worth (value of money now)
$F$: Future Worth (value of money at a future date)
$A$: Annuity (uniform series of payments)
$i$: Interest rate per period (usually in decimal form, e.g., 12% = 0.12)
$n$: Number of periods (years, months, etc.)

Problem 2: Present Worth (Discounting)

Problem: A certain machine will be worth P100,000 after 10 years. If money is worth 6% compounded annually, how much should you invest now to have that amount in the future?

Solution:

Given: $F = 100,000$, $i = 0.06$, $n = 10$, Find $P$.
Formula: $P = F(1 + i)^-n$
Calculation: $$P = 100,000 (1 + 0.06)^-10$$ $$P = 100,000 (0.55839)$$ $$P = 55,839.48$$
Answer: P55,839.48

Where to Find Legitimate Copies of the Solution Manual
