Next batch:
easy = 322 = 2 elephant, 1 chariot, 2 khopesh
medium = 395 = 2 elephant, 4 khopesh
hard = 419 = 3 chariot, 3 camel + 1 chariot, 3 camel
Assuming
1 elephant = 93.25 loot
1 chariot = 30.125 loot
1 archer = 74.41666_ loot
(395 - 2(93.25))4 = 52.125
322 - 2(93.25) - 2(52.125) = 31.25
but
(322 - 2(93.25) - 30.125)/2 = 93.8125
That's pretty close; the values are within 1.125 of each other.
Alternatively:
322 = 2x+y+2z ; 395 = 2x+4z. 2x = 395-4z. 322 = 395-4z+y+2z. 2z = 395-322+y. z = (73+y)/2
If chariots are 30.125, then khopesh are 51.5625. If chariots are 31.25, then khopesh are 52.125.
(419-4x)/6 = y.
If chariots are 30.125, then camels are 49.75. If chariots are 31.25, then camels are 49.
So the numbers don't quite add up yet, but tentatively:
1 elephant = 93.25 loot
1 archer = 74.41666_ loot
1 khopesh = 51.5625 or 52.125 loot
1 camel = 49 or 49.75 loot
1 chariot = 30.125 or 31.25 loot
