after hitting the black friday sales, sarah bought her dress on sale for $35. She saved 45%, what was the original cost.

8090 [49]

The original cost of the dress is $63.64

Step-by-step explanation:

After hitting the black Friday sales

Sarah bought her dress on sale for $35
She saved 45%

We need to find the original cost of the dress

The money that Sarah saved is the value of the discount on the dress

Assume that the price of the dress before the black Friday is 100%

∵ The price of the dress before the black Friday is 100%

∵ She saved 45% when she bought it the black Friday

∴ The price of the dress is decreased by 45%

∵ She bought the dress for $35 ⇒ (after discount)

Let use use the percentage method

→ Before discount : Discount : After discount

→ 100% : 45% : 55% (100 - 45)

→ x : : 35

By using cross multiplication

∵ x × 55% = 35 × 100%

- Divide both sides by 55%

∴ x = 63.64

The original cost of the dress is $63.64
