Answer:

The purchase price was $30.14 rounded to the nearest penny.

Explanation:

The formula to find the total price of a product plus the sales tax is:

#T = p + s*p# where #T# is the total price, #p# is the price of the product and #s# is the sales tax percent. Substituting what is provided gives:

#32.85 = p + 9%p#

#32.85 = p + 0.09p#

#32.85 = 1.09p#

#32.85/1.09 = (1.09p)/1.09#

#p = 30.14# rounded to the nearest penny.
