An item is regularly priced at $81.It is on sale for 45% off the regular price. Find the sale price.

To find the sale price, we need to multiply the regular price by the discount percentage and then subtract that amount from the regular price.

Discount amount = 81 * 45% = 81 * 0.45 = $36.45

Sale price = Regular price - Discount amount = 81 - 36.45 = $<<81-36.45=44.55>>44.55

Therefore, the sale price is $44.55.
