Cost of rug during sale = $140
Step-by-step explanation:
Given
Marked price of rug in a store = $200
The store is holding a sale and offering a flat 30% less on marked price on all items
This means the sale price of all items would decrease by 30%
We can calculate the discount offered by taking out percentage discount of the marked price.
Discount offered on rug = 30% of Marked price 
The discount is then subtracted from the marked price to get the price of rug during sale.
∴ Price of rug during sale = Marked price - Discount
