0.8x – 12
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
Answer:
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 [tex]x-15[/tex].
Then 20% discount is applied, so the final price of the jacket is
[tex]P=(x-15)(1-\frac{20}{100})[/tex]
[tex]P=(x-15)(1-0.2)[/tex]
[tex]P=(x-15)(0.8)[/tex]
[tex]P=0.8x-12[/tex]
The final price of the jacket during this sale is 0.8x-12. Therefore the correct option is B.
