For this project, each group needs to implement a system to calculate global taxing (additional tax to pay to IRS USA) for someone who holds US citizenship or green card but has income from either Hong Kong or Macau or both.Please do let the user choose:
Income sources (HKD, MOP, or both, or even with USD income as well)
Status (Single or Married)
Age for Macau (if Age >= 65, then exemption amount is different)

Also, do allow user to enter income amount in (HKD, MOP, and USD) and exchange rates between USD and HKD as well as USD and MOP.All the tax bracket (tax rates) already provided in the documents that I sent to you before.Please do also search for additional information to improve your system as close as possible to the actual situation in the real world, for example, for total income less than a certain level, no global taxing will be charged.

Bonus points (3 points)
To create an APP for your Global Tax Calculation.
