Today I tried to calculate the income of a building.

The building has 1 small emerald: + 5%

I have 2 totems of prosperity on my island: + 20%

I also hired the  accountant in the administrative building: + 5%

All together: + 30%

So first I thought the income will increase by multiplying with the factor 1.3.

In fact the income is to multilpy with 1.323 ! So the correct formula in this case is:

(1 + 5%) * (1 + 20%) * (1 + 5%) = 1.323
