At a pizzeria, a pizza has a regular price of x dollars. During a sale, the price of the pizza is discounted by 15%. The expression 0.85x describes the discounted price, in dollars, of the pizza. Which expression also describes the discounted price, in dollars, of the pizza?
Responses
A x – 0.85xx – 0.85 x
B x – 15xx – 15 x
C 85x85 x
D x – 0.15xx – 0.15 x
D x – 0.15x
The correct expression that describes the discounted price, in dollars, of the pizza is:
D) x - 0.15x
To find the discounted price of the pizza, we need to apply a 15% discount to the regular price.
To do this, we can use the equation:
Discounted Price = Regular Price - (Discount Percentage × Regular Price)
In this case, the discount percentage is 15% or 0.15. So the expression for the discounted price, in dollars, of the pizza would be:
Discounted Price = x - (0.15 × x)
Simplifying, we get:
Discounted Price = x - 0.15x
Comparing this expression to the given options:
A) x - 0.85xx - 0.85x: This expression is not equivalent to what we just found.
B) x - 15xx - 15x: This expression is not equivalent to what we just found. It uses the number 15 instead of the discount percentage 0.15.
C) 85x85 x: This expression is incorrect and does not give the discounted price.
D) x - 0.15xx - 0.15x: This expression is identical to the one we found:
Discounted Price = x - 0.15x
Therefore, the correct answer is option D.
