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.
1. s = p – 0.25p; $30
2. s = p – 25; $15
3. s = p – 0.25p; $10
4. s = p – 0.25; $39.75
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.
The correct expression that represents the sale price is:
s = p - 0.25p
where s represents the sale price and p represents the original price.
To evaluate the expression for an original price of $40, we substitute p = 40 into the expression:
s = 40 - 0.25(40)
s = 40 - 10
s = 30
Therefore, the sale price of the jeans is $30.
The correct option is:
1. s = p – 0.25p; $30
