It's not about the percentage, but how the adjusted cost is calculated - the incorrect cost of 93 fuel for Puma is achieved by multiplying it's cost by 1.33, while I should have been divided by 0.66 (or 0.(6) depending on how precise you want to be).
LOL cmon guys is math really that hard
93 fuel was achieved by correctly assuming the base cost of the puma was 70 instead of 80 and correctly multiplying by 1.33
106 fuel was achieved by incorrectly assuming the base cost of the puma was 80 and multiplying by 1.33
dividing 80 by 0.67 is the same as multiplying by 1.5 and yields 120, which is completely wrong.
