The dress is on sale for 35% off the regular price (w). What expression represents the sale price of the wedding dress?
Aleonysh [2.5K]

Expression that represents the sale price of the wedding dress is s = 0.65w

<em><u>Solution:</u></em>

Given that, the dress is on sale for 35 % off the regular price

Let the regular price of dress be "w"

To find: Expression that represents the sale price of the wedding dress

Let "s" be the sale price of wedding dress

Sale price = Regular price - discount price

<em><u>Discount price is given as:</u></em>

Discount price = 35 % of regular price

Discount price = 35 % of w

\rightarrow 35 \% \times w\\\\\rightarrow \frac{35}{100} \times w\\\\\rightarrow 0.35w

Thus discount price = 0.35w

<em><u>Expression for the sale price of the wedding dress:</u></em>

Sale price = Regular price - discount price

s = w - 0.35w

s = 0.65w

Thus expression that represents the sale price of the wedding dress is s = 0.65w
