Formula
Income is determined by this formula:


 * $$ Individual\ Income = [\$ 30\ +\ (\$ 2\ \times\ Happiness)\ + \sum_{} (\$\ Bonuses) ]\ \times\ \prod_{} (1\ +\ (\%\ Bonuses)) $$

Example
You have 17 happiness, Gems (+ $1.50 income), Furs (+ $3.50 income), a Foreign Ministry (+ 5% income), and 2 Banks (+ 7% income).


 * $$ Individual\ Income = \left [\$ 30\ +\ (\$ 2\ \times\ 17)\ +\ \$ 1.50\ +\ \$ 3.50 \right ]\ \times\ 105\%\ \times\ 107\%\ \times\ 107\% = \$ 82.95$$
