Question

In C++ Write a function that has an double as a parameter and returns a double through the function call. (Be Original)
                                           

The parameter is the income for a single person and the return value is the amount of income tax owed.

                                             Use the Schedule X – Single table below.              

                                             
                                            Write a main function to test the function you have written.

                                             You are required to used

                                                                nested if … else if … else if … else

                                                                to determine the calculation to use for the tax.

If taxable income is  over--	But not over--	The tax is:
$0	$7,550	10% of the amount over $0
$7,550	$30,650	$755 plus 15% of the amount over 7,550
$30,650	$74,200	$4,220.00 plus 25% of the amount over 30,650
$74,200	$154,800	$15,107.50 plus 28% of the amount over 74,200
$154,800	$336,550	$37,675.50 plus 33% of the amount over 154,800
$336,550	no limit	$97,653.00 plus 35% of the amount over 336,550
