float calculateTaxes(income, brackets)
where "brackets" is a list of pairs, e.g.
[
[5000, 0],
[10000, 0.1],
[20000, 0.2],
[10000, 0.3],
[null, 0.4],
]
This indicates that:
The first $5K is untaxed
The next $10K is taxed at 10%
The next $20K is taxed at 20%
The next $10K is taxed at 30%
All income above this is taxed at 40%
So, for an income of $55K, the tax would be $0K + $1K + $4K + $3K + $4K = $12K.
