Question

A sporting goods store is having a 15% off sale on all items. Which functions can be used to find the sale price of an item that has an original price of x? You may choose more than one correct answer.

y = .85 x
ƒ( x) = 1.15 x
Sale = Original - 15
ƒ( x) = x - .15 x
Sale = Original - .15(Original)

Answer 1

Answer:The answer will be D and E

Step-by-step explanation:

Taking 15% off is the same thing as only charging 85% so both D and E are correct

Answer 2

Answer:

only [D] part

Step-by-step explanation:

let we take original price of all goods = 100 = [x]

discount % on each goods = 15%

let the original price of all goods = 100 -- 15% of 100

= 100 -- 15/100 x 100

= 100 -- 15

= 85 Ans
