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?
Explain your answer

1 answer

On the first day of the sale, the price of the item is reduced by 10%, so it becomes $10.00 - $1.00 (10% of $10.00) = $9.00.

On the second day of the sale, the price of the item is reduced by 10% from the previous day's price, so it becomes $9.00 - $0.90 (10% of $9.00) = $8.10.

On the third day of the sale, the price of the item is reduced by 10% from the previous day's price, so it becomes $8.10 - $0.81 (10% of $8.10) = $7.29.

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