Hall and Klitgaard approach economic history as a sequence of technical and political arrangements to deal with energy. Indeed, they see energy as the single non-substitutable factor of production.

The key issue for them is Energy Return on Energy Invested. How do they calculate EROEI?

a EROI = Energy Output/Energy Input
b EROI = Energy Input/Energy Output
c EROI = Energy Output divided by the price of energy
d EROI = Energy Input divided by the price of energy

Perry is a freshman, he estimates that the cost of tuition, books, room and board, transportation, and other incidentals will be $30000 this year. he expects these costs to rise about $1500 each year while he is in college. if it will take him 5 years to earn his bs, what is the present cost of his degree at an interest rate of 6%? if he earns and extra $10000 annually for 40 years, what is the present worth of his degree.?
