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 percent 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 ? a. x=y=z
b. x=y c. x d. x e. y

B. x=y

Step-by-step explanation:

Store X applies its discount of 5% first and then charges tax of 5% on the discounted price. The discount is 5/100× x = 0.05x. The new amount is x - 0.05x = 0.95x

Tax charged on 0.95x = 5/100× 0.95x = 0.0475

Final amount at store x = 0.95x + 0.0475x = 0.9975x

Store Y adds the tax first and then applies the discount to the price with tax.

Tax charged on y = 5/100× y = 0.05y.

Price with tax = y + 0.05y = 1.05y

5% discount on 1.05y = 5/100 × 1.05y = 0.0525y

Final amount at store y = 1.05y - 0.0525y = 0.9975y

The final price at store Z remains z

The final prices at store X and store Y are 0.9975 of the initial prices. Therefore, X = Y describes the relationship among x, y, and z

the median here is 25. your lowest value is 14 and highest value is 48. to find the third quartile, find the medium number in between 25 and 48 which would be 42 i believe.

this linear equation would have just one solution.

step-by-step explanation:

the reason why this would have one solution is that it is an expression with just one variable. since that variable is not raised to a power, it will always have just one solution.
