Determining the most efficient use of capital ?

[Aston08]

How would I calculate which of the 2 options is the most efficient use of the capital?


With $5,000 of capital ...


1.) I can purchase and resell 20 units for a $1000 profit

2.) I can purchase and resell 200 units for a $1500 profit


Obviously option #2 is the most profitable but also requires 10x the work. Option #1 has a better profit margin, but less return on investment.

Outside of determining which aspect is more important that the other, is there a way to determine which is the most efficient use of the capital with the given information? ..or am I missing another variable ?

Consider the work involved, ie assign an hourly rate of x dollars, or use a commission per item sold rate.
