A pair of jeans is on sale for 25% off the original price. Which expression represents the sale price? If the original price of the jeans is $40, evaluate the expression to find the sale price.

Question

1. s = p – 0.25p; $30
2. s = p – 25; $15
3. s = p – 0.25p; $10
4. s = p – 0.25; $39.75

Answer 1

The correct expression that represents the sale price is 1. s = p – 0.25p.

To find the sale price, you need to substitute the original price, p = $40, into the expression and evaluate it:

s = 40 - 0.25 * 40
= 40 - 10
= $30

Therefore, the sale price of the jeans is $30, which matches option 1.
