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% of 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?

Day 1:

$10.00 - 10% = $9.00

Day 2:
$9.00 * 90% = $8.10

Day 3:
$8.10 * 90% = $7.29

Therefore, the price for the item on the 3rd day of the sale is $7.29.
