Question is Incomplete; Complete question is given below;
Chase purchased a sweatshirt from the clearance rack. The price of the sweatshirt after the discount is represented by the expression 0.75x, where x represents the original price of the sweatshirt.
Which expression also represents the discounted price of the sweatshirt?
A (0.75 − 0.25)x
B (0.75 + 0.25)x
C x – 0.25x
D x + 0.25x
Answer:
C
.
Step-by-step explanation:
Given:
Expression representing price of the sweatshirt after the discount =
⇒ original price of sweatshirt
We need to find the expression which also represents the discounted price of the sweatshirt.
Solution:
Form the given expression we can see that after discount we are paying only 75% of the original amount of sweatshirt.
So we can say that;
The discount price was 25% of the original price i.e
So now we can say that;
Price after discount is equal to difference of original price and discounted price.
framing in equation form we get;
Price after discount =
Hence the equivalent expression for the given discounted price of sweatshirt is .
