Write a VBA Function subroutine called Tax that takes a single argument grossIncome of type Currency. It should calculate the tax on any income using the following tax schedule: (1) if income is less than or equal to $15,000, there is no tax (2) if income is greater than $15,000 and less than or equal to $75,000, the tax is 15% of all income greater than $15,000 (3) if income is greater than $75,000, the tax is 15% of all income between $15,000 and $75,000 plus 20% of all income greater than $75,000 Then write a CalcTax subroutine that asks the user for his income, gets the function subroutine to calculate the tax on this income, and reports the tax in a message box.
