if a gift is 42.40 including tax,what is the retail price for the gift if the sales tax is 6% ??

  • math -

    Set up a ratio. The cost of the gift including tax is 106% of the cost without tax.

    42.40/106 = x/100

    Solve for x.

    (Note it does not matter whether you use 1.06 or 106 for the percentages in the ratio as long as you are consistent).

  • math -

    1.06x = 42.4

    x = 42.4 / 1.06
    x = ?

  • math -

    42.40 = X * 1.06
    where X is the retail price

    X = 42.40/1.06 = $40.00
