  5.  * COMPUTE TOTAL SALES TAX
  6.  * _________________________________________________________________________
  7.  * This program computes the total sales tax on a purchase based on
  8.  * the sales tax and county sales tax rates.
  9.  * 
  10.  * Computation is based on the formulas:
  11.  * State Tax  = Purchase Amount x Sales Tax Rate
  12.  * County Tax = Purchase Amount x County Tax Rate
  13.  * Total Tax  = Sales Tax + County Tax
  14.  * _________________________________________________________________________
  15.  * INPUT
  16.  *   purchaseAmount : Total amount of the purchase ($52)
  17.  *   salesTaxRate   : State sales tax percentage (4%)
  18.  *   countyTaxRate  : County sales tax percentage (2%)
  19.  * 
  20.  * OUTPUT
  21.  *   stateTax       : Amount of state sales tax
  22.  *   countyTax      : Amount of county sales tax
  23.  *   totalTax       : Total sales tax calculated
