Acomputer cost 1389.93 including tax if the tax rate is 7% find the price of the computer before taxes

Cost of the computer before taxes is $1299.

Step-by-step explanation:

Let the price of the computer before taxes is = $x

Tax rate on this computer = 7%

Therefore, computer cost including tax = (x + 7% of x)

                                                                 =

                                                                 = x + 0.07x

                                                                 = $(1.07x)

Cost of the computer including tax is given as $1389.93.

Therefore, 1389.93 = 1.07x

x =

  = $1299

Cost of the computer before taxes is $1299.
