A jewelry store bought a gold necklace and marked it up 110% from the original

Question

A jewelry store bought a gold necklace and marked it up 110% from the original cost of $23.52. Later on, Dean purchased the gold necklace and paid 14.75% sales tax. How much, including tax, did he pay for the gold necklace? this is the question

Answer 1

23.52 (1.1) = 25.872 (1.1 = 110%)

25.875(1.1475) = 29.688 = $29.69 = total purchase price

(1.1475 = 1 + .1475 = the cost + the tax)

with a 14.75 sales tax, this must be NYC? not the gas tax they don't itemize, so you don't know you're paying it? sales taxes have traditionally been considered "regressive" impacting the poor more than the wealthy. But if it's a "luxury" tax, a sales tax on luxury items, like gold, that's not true at all.
