Jackson’s translated value scale would be:
1. A – 3rd horse
2. D,E,F,G – 4 barrels of fish
3. D,E,F – 3 barrels of fish
4. B – 2nd horse
5. D,E – 2 barrels of fish
6. C – 1st horse
7. D – 1 barrel of fish
This value scale assumes that his horses come in equally-serviceable units and that his barrels of fish come in equally-serviceable units. Equally-serviceable units of a good mean that any one unit can satisfy any one end. So 4 barrels of fish allow Jackson to satisfy his four highest-valued ends (D,E,F,G).
