You may assume that:

• The types of the values that are sent to the functions are the proper ones, you dont have

  to validate them

• The functions are going to be called with usable values. Income and tax rate wont have

  negative values, etc.

• Minimum amount is 1 cent. Fractions of it should be rounded to closest cent.

• A married person cannot le as single

• A single parent will le as single

• A couple has the option to le either jointly or separately

• When a couple is ling separately both of them are still counted as family_members

exemption(income, ling_status, family_members)

Description: It returns the part of the income that is "exempted" from taxation. Obviously, it cant be higher than the income.

Parameters: income ( oat) is the amount of income in dollars. ling_status (integer) is the status of the ling person: 1=single, 2=married ling jointly, 3=married ling separately. family_members (integer) is the total number of family members (if parents are ling separately both of them are still counted in family_members)

Return value: The amount ( oat) of the income that is exempted.

Logic: The base exemption is $3000 for the ling person and $2000 for each child. If a couple is ling jointly, both spouses are eligible for the exemption. If the income is above $100,000 the parents exemption is reduced by 0.5% per whole thousand dollars of income above 100K. Regardless of the income, though, this reduction cannot exceed 30%. If the family has more than two children, the child exemption is reduced by 5% for each additional child (i.e. for 3 kids -5%, for 4 kids -10%, and so forth). Regardless of the number of children, though, the childs exemption cannot be reduced more than 50%.

Examples:

exemption(11500.67, 1, 1) 3000.00 exemption(17230.18, 1, 3) 7000.00
