A store is having a three day sale. On the first day of the sale, the price of an item is reduced by 10%from its regular price.
Each day of the sale after the first day, the price of each sale item is reduced to equal 90% off its price from the previous day.
One sale item has an original price of $10.00.
What is the price for the item on the 3rd day of the sale
On the first day of the sale, the item is reduced by 10%, making the price $9.00.
On the second day of the sale, the price is reduced by 90% of $9.00, which is $0.90. So, the price on the second day is $9.00 - $0.90 = $8.10.
On the third day of the sale, the price is reduced by 90% of $8.10, which is $0.81. So, the price on the third day is $8.10 - $0.81 = $7.29.
Therefore, the price for the item on the 3rd day of the sale is $7.29.
