Country X calculates tax for its citizens using a graduated scale rate as shown below:
Yearly Income: 0 - 1000
Tax Rate: 0%
Yearly Income: 1,001 - 10,000
Tax Rate: 10%
Yearly Income: 10,001 - 20,200
Tax Rate: 15%
Yearly Income: 20,201 - 30,750
Tax Rate: 20%
Yearly Income: 30,751 - 50,000
Tax Rate: 25%
Yearly Income: Over 50,000
Tax Rate: 30%
Write a Python function named calculate_tax that will take as an argument, a dictionary containing key-value pairs of people's names as the keys and their yearly incomes as the values.
The function should return a dictionary containing key-value pairs of the same people’s names as keys and their yearly tax bill as the values. For example, given the sample input below:
{
‘Alex’: 500,
‘James’: 20500,
‘Kinuthia’: 70000
}
The output would be as follows:
{
‘Alex’: 0,
‘James’: 2490,
‘Kinuthia’: 15352.5
}
