Stores X,Y and Z each sell a certain item that has a given list price. Stores X and Y are located in a state with a 5% percent sales tax, and both sell the item at a 5% discount off list price, while store Z is located in a state with no sales tax and gives no discounts. Store X applies its discount first and then charges tax on the discounted price, while store Y adds the tax first and then applies the discount to the price with tax. If x and y are the prices, with tax and discount, charged by stores X and Y, respectively, and z is the price charged by Store Z, which of the following statements correctly describes the relationship among x,y and z ?
x=y=z : x=y<z : x<y<z : x<z<y : y<z<x
In my mind x cannot equal to y. So I'm quiet lost indeed.
Any help will be more then welcome
