Question

2. 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.
Os=p-0.25p; $30
Os=p-25; $15
Os=p-0.25p; $10
Os p-0.25; $39.75

Answer 1

Answer: s = p - 0.25p; $30

Explanation:

First, we need to know that a percent divided by 100 becomes a decimal.

25% / 100 = 0.25.

Next, we will use this equation because it takes 25% off of the original price (p) by subtracting 0.25p from p.

s = p - 0.25p

Lastly, we will substitute 40 in for 0 and solve.

s = ($40) - 0.25($40)

s = $30
