Question

A jacket is on sale for $15 off. As part of a one-day sale, a 20% discount is applied to all purchases. If x represents the original price of the jacket, which expression represents the final price of the jacket during this sale? 0.2x – 3 0.8x – 12 0.8x – 15 0.2x – 15

Answer 1

The correct option is B.

Step-by-step explanation:

Let the original price of the jacket be x.

A jacket is on sale for $15 off. As part of a one-day sale, a 20% discount is applied to all purchases.

The price of jacket after $15 off is
`x-15`.

Then 20% discount is applied, so the final price of the jacket is

`P=(x-15)(1-(20)/(100))`

`P=(x-15)(1-0.2)`

`P=(x-15)(0.8)`

`P=0.8x-12`

The final price of the jacket during this sale is 0.8x-12. Therefore the correct option is B.

Answer 2

0.8x – 12

Step-by-step explanation:

The sale price is (x-15). After the 20% discount, the final price is 0.80 times the sale price, so is ...

... final price = 0.80×(x -15) = 0.80x -12
