Answer:   The exact answer is: $ 39,856 approaching: $ 40.00

Explanation:  

First,  the value of the sales tax corresponding to 6% is determined:             $ 42.4  x  0.06  =  $  2,544

Now subtract $ 2,544 from the total value of the purchase

               $ 42.4 - $ 2,544 = $ 39,856 approx. $ 40.00 this is the value of the pre-tax gift
