How to calculate 30 Percent-off

Now, let's solve the questions stated above:

1) What is 30 percent off £100? Find the amount of discount.

Suppose you have a Kohls coupon of £100 and you want to know how much you will save for an item if the discount is 30 percent.

✅Solution:

Replacing the given values in formula (a) we have:

Amount Saved = Original Price x Discount in Percent / 100. So,

Amount Saved = 100 x 30 / 100

Amount Saved = 3000 / 100

Amount Saved = £30 (answer).

In other words, a 30% discount for a item with original price of £100 is equal to £30 (Amount Saved).

Note that to find the amount saved, just multiply it by the percentage and divide by 100.

2) How much to pay for an item of £100 when discounted 30 percent (%)? What is item's sale price?

✅Solution:

Suppose you have a L.L. Bean coupon of £100 and you want to know the final or sale price if the discount is 30 percent.

Using the formula (b) and replacing the given values:

Sale Price = Original Price - Amount Saved. So,

Sale Price = 100 - 30

Sale Price = £70 (answer).

This means the cost of the item to you is £70.

You will pay £70 for a item with original price of £100 when discounted 30%.

In this example, if you buy an item at £100 with 30% discount, you will pay 100 - 30 = 70 pounds.

3) 30 is what percent off 100 pounds?

✅Solution:

Using the formula (b) and replacing given values:

Amount Saved = Original Price x Discount in Percent /100. So,

30 = 100 x Discount in Percent / 100

30 / 100 = Discount in Percent /100

100 x 30 / 100 = Discount in Percent

3000 / 100 = Discount in Percent, or

Discount in Percent = 30 (answer).
