The market sells only a few items:
Apples @ 99 cents each
Gas @ $3.59 per gallon
Cookies @ $1.99 per package (taxed) 
Gum @ 99 cents per package (taxed)
Allow the user to keep entering in items until Q is entered.
Calculate the subtotal for the transaction without tax.
Calculate the total after adding 7% tax to the taxed items (see above).
Display the subtotal and total.
Keep a cumulative total of the quantity of each item sold.
Keep a record of each of the transactions.
After the user enters "Q" and quits the transaction, return to the main menu.  Allow the user to view the total of all the sales (including tax), the total tax collected, the quantity of each item sold and the average sale (including tax).  When the user enters 6, the program ends.
