s = p – 0.25 p ; $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 find the sale price when the original price is $40, you substitute p = 40 into the expression:
s = 40 - 0.25(40)
s = 40 - 10
s = 30
So, the sale price is $30.
To find the sale price, we need to find 25% of the original price and subtract it from the original price.
In this case, the original price is $40, so we want to find 25% of $40.
To find 25% of a number, we multiply the number by 0.25.
So, 25% of $40 is $40 * 0.25 = $10.
Now, we subtract $10 from the original price of $40 to get the sale price.
So, the expression that represents the sale price is s = p - 0.25p.
Evaluating this expression, we substitute p with $40:
s = $40 - 0.25 * $40 = $40 - $10 = $30.
Therefore, the correct expression and sale price is s = p - 0.25p; $30.
The expression that represents the sale price is s = p - 0.25p.
Now let's evaluate the expression with p = $40:
s = 40 - 0.25(40)
s = 40 - 10
s = $30
Therefore, the sale price of the jeans is $30.
