    Answer: $100.12

    Step-by-step explanation:

    Hi, to answer this question, first, we have to multiply the regular price of the pair of shoes by the percent discount in decimal form (divided by 100)

    127 x (28/100) =

    127 x (0.28) = $35.56 (amount of the discount)

    Next, we have to subtract the discount to the regular price

    127-35.56 = $91.44 (discounted price)

    Tax: 9 1/2 % = (9x2+1) / 2 = 19/2 = 9.5%

    We have to multiply the discounted price by the tax percentage (decimal form)

    91.44 x (9.5/100) =

    91.44 x 0.095 = $ 8.68 (tax amount)

    Finally we have to add that amount to the discounted price:

    91.44 + 8.68 = $100.12
