Question

Salesure is a social media marketing startup. They have 10 employees working on a casual basis. Being a small company, Salesure do not have resources to purchase professional payroll software. They have hired you to write a simple Python program that can work out the amount of tax to withhold from their employee salaries.

Employees are payed fortnightly, and because of casual nature of the job each fortnight the payment is different. The amount of withheld tax depends on the gross payment in each fortnight, and the income tax rates for the corresponding income bracket.

Following are the income tax rates advised by Government Taxation Department. Gross annual income should be rounded down to nearest dollar before any tax calculation.

Annual Taxable Income	Tax Percentage
0 to 15,000	5%
15,001 to 40,000	15%
40,001 to 90,000	28%
90,001 to 150,000	21%
150,000 and over	13%

An example of withheld tax calculation goes like this. Sam is entitled to fortnightly payment of $1870. To calculate income tax applicable, an estimate of Sam's annual income is needed. There are 52.143 weeks in a year. An estimation of annual income will therefore be $1870 × 52.143 / 2 = $48,753.705 or $48,753 after rounding down. From the table, the applicable tax rate is 28%. Hence, the amount of tax to withhold will be 28% of $1870 = $523.60, and Sam will be payed an after-tax salary of $1346.40 in this fortnight.

Using this method, your program will ask the user for the employee name and their gross fortnightly salary, and then it will work out the tax to withhold and actual salary to be payed out. At the end of a calculation, program would ask if user wants tax calculation of another employee (in which case it loop through the whole process) or finish.

You do not have to handle invalid inputs (like non-numeric salary, empty name etc.). All the currency figures must be displayed as floating point numbers with 2 decimal places.

Below is a sample execution of the program. You should follow the same display style.
