Monthly Sales Tax - A retail company must file a monthly sales tax report listing
the sales for the month and the amount of sales tax collected. Write a program that
asks for the month, the year, and the total amount collected at the cash register 
(that is, sales plus sales tax). Assume the state sales tax is 4 percent and the
county sales tax is 2 percent. If the total amount collected is known and the total
sales tax is 6 percent, the amount of product sales may be calculated S=T/1.06
where S is the product sales and T is the total income (product sales plus sales tax).
