s = p – 0.25p; $30
s = p – 25; $15
s = p – 0.25p; $10
s = p – 0.25; $39.75
The correct expression that represents the sale price is s = p - 0.25p.
To evaluate the expression, we can substitute p = $40 into the equation:
s = 40 - 0.25(40)
s = 40 - 10
s = $30
Therefore, the sale price of the jeans is $30.
what is the answer
The answer is s = p - 0.25p; $30.

To simplify the expression, we can perform the operations within the parentheses first:
Start fraction 5 squared is equal to 25.
So the expression becomes: start fraction 25 minus 4 over 5 plus 2 end fraction.
Next, we simplify the expression within the parentheses:
- Start fraction 25 minus 4 is equal to 21.
- Start fraction 21 over 5 plus 2 is equal to start fraction 21 plus 10 over 5 end fraction, which equals 31 over 5.
Therefore, the simplified expression is 31 over 5.
Simplify the following expression: start fraction 5 squared minus 4 over 5 plus 2 end fraction.

So, the correct answer is not "3".
so what is the answer
The correct answer is: start fraction 31 over 5 end fraction.
To find the expression that represents the sale price, we need to subtract the discount from the original price.
The expression s = p - 0.25p represents the sale price, where s is the sale price and p is the original price.
Substituting the given original price of $40 into the expression, we have:
s = 40 - 0.25(40)
s = 40 - 10
s = $30.
Therefore, the correct expression is s = p - 0.25p, and the sale price is $30.
