Including 6.6% sales tax a diamond ring sold for 2132. find the price of the ring before the tax was added.

The amount of tax = 6.6/100 *2132
                              = 140.712
Original price of diamond ring = 2132 - 140.712
                                                = 1961.288
 
In short, your answer should be 1961.288.

Hopefully this helped :)
