need help with my economics paper

MOH + DL + DM = COGS

Marketing, admin, RnD etc. also called overheads.

When ppl say overheads are included in COGS, do they only mean manufacturing overheads?

Why the unnecessary confusion?

This is more like cost accounting than economics.

that's not economics ...

The answer is......it depends.

If you don't even understand what subject you are studying, how to do your homework?

How?

Why?

I shall not detract from your use of acronyms.

It depends on AC or MC.
