using else-if ladder find the net tax paid by an employee.
The progressive income tax rate is mandated as follows:
| Taxable Income | Rate (%) |
|---|---|
| First $20,000 | 0 |
| Next $20,000 | 10 |
| Next $20,000 | 20 |
| The remaining | 30 |
For example, suppose that the taxable income is $85,000 , the income tax payable is:
$20,000 * 0% + $20,000 * 10% + $20,800 * 20% + $25,890 * 30%
