what is the rate of discount if a sweater regularly priced at $45. and sold for $36.

what is (45-36)/45 x 100?

To calculate the rate of discount, follow these steps:

Step 1: Determine the original price and the sale price.
Original price = $45
Sale price = $36

Step 2: Calculate the amount of discount.
Discount = Original price - Sale price
Discount = $45 - $36
Discount = $9

Step 3: Calculate the rate of discount.
Rate of discount = (Discount / Original price) x 100
Rate of discount = ($9 / $45) x 100
Rate of discount = 0.2 x 100
Rate of discount = 20%

Therefore, the rate of discount on the sweater is 20%.

To calculate the rate of discount, you need to find the difference between the regular price and the sale price, then express that difference as a percentage of the regular price. Here's how to calculate it:

Step 1: Find the difference between the regular price and the sale price.
Regular price = $45
Sale price = $36
Discount = Regular price - Sale price = $45 - $36 = $9

Step 2: Express the discount as a percentage of the regular price.
Discount percentage = (Discount / Regular price) * 100
Discount percentage = ($9 / $45) * 100 ≈ 0.2 * 100 ≈ 20%

Therefore, the rate of discount for the sweater is 20%.
