Actually, most of them tend to have exactly that phrase in their title. Count me in the group who wishes far too late that he had held onto his copy instead of selling it at a discount to another student.

I think any introductory textbook on Managerial Economics would cover the same material. It's just that Engineering Economics books tend to use industrial plants and machinery for most of their examples.

Apparently I did not keep my textbook, and don't remember which one I had.

This one[1] is probably decent (looking at its table of contents):

It's not a sophisticated topic. If you're a non-CS engineer who knows calculus and algebra well, this is one of the easiest topics in the curriculum.

Even if your calculus is poor, simply using the concepts with a spreadsheet will get you almost all the way.
