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 is to find the sale price
There are two ways to look at sales.
1) As the original price (P) - Px.25
or
2) as 0.75P that is 75% of the original price is the new price
so
if the jeans were $40, the new price is .75(40)
To find the sale price of a pair of jeans that is discounted by 25% off the original price, you can use the following expression:
Sale Price = Original Price - (Original Price * Discount Percent)
Given that the original price of the jeans is $40 and the discount percent is 25%, the expression becomes:
Sale Price = $40 - ($40 * 0.25)
To evaluate the expression, you need to calculate the values within the parentheses first:
$40 * 0.25 = $10
Now substitute the calculated value back into the expression:
Sale Price = $40 - $10
Finally, subtract the calculated amount from the original price:
Sale Price = $30
Therefore, the sale price of the jeans after a 25% discount is $30.
