Identify which among principle of Engineering Economics it is:
Carefully define the problem! Then the choice (decision) is among alternatives. The alternatives need to be identified and then defined for subsequent analysis.
Develop Alternatives
Focus on Differences
Use a consistent point of view
Use a common unit of measure
Identify which among principle of Engineering Economics it is:
Enumerate as many of the prospective outcomes as possible will simplify the analysis of the alternatives.
Develop Alternatives
Focus on differences
Use a consistent point of view

What is the formula for calculating compound interest?
A = P(1 + r/n)^(nt)
A = P(1 + r/n)^(nt) - P
A = P(1 + r)^(nt)
A = P(1 + r/n)^(t)
What is the formula for calculating simple interest?
I = P * R * T
I = R * T
I = P * T
I = P * R
