Today a clothing store took 30% off the price of a dress, and for the next 3 days, it will take 30% off the previous day's price. if the price of the dress yesterday was $300.00, what will be the price of the dress 3 days from now?

To find the price three days from now you can calculate the price of the dress after applying the discount each day.

To find the new price, you can multiply by 0.7 (100%-30% = 70%/0.7).

300 x 0.7 = 210 (now)
1st day: 210 x 0.7 = $147
2nd day: $147 x 0.7 = $102.90
3rd day: 102.9 x 0.7 = $72.03

The price on the third day is $72.03.
