You want to buy three books that are on sale at 20% off. The original prices of the books are $2.50, $4.95, and $6.00. How much will you save?

20% = 20 / 100 = 0.2

You will save:

0.2 ∙ ( $2.50 + $4.95 + $6.00 ) = 0.2 ∙ $13.45 = $2.69

Is that with or with out distribution

That is with distribution.

To calculate how much you will save, you'll first need to find the discounted price of each book, and then compare it to the original price. Here's how to do it:

1. Calculate the discount: The discount is given as 20%, which means you will pay 80% of the original price for each book. To calculate the discount, multiply the original price by 0.20:

20% discount = 0.20
Discount amount for the first book = $2.50 * 0.20
Discounted price for the first book = $2.50 - (discount amount)

2. Repeat the steps above for the remaining two books:

Discount amount for the second book = $4.95 * 0.20
Discounted price for the second book = $4.95 - (discount amount)

Discount amount for the third book = $6.00 * 0.20
Discounted price for the third book = $6.00 - (discount amount)

3. Calculate the total savings: To find the total savings, subtract the sum of the discounted prices from the sum of the original prices:

Total original price = $2.50 + $4.95 + $6.00
Total discounted price = (Discounted price for the first book) + (Discounted price for the second book) + (Discounted price for the third book)
Total savings = Total original price - Total discounted price

Now you can follow these steps to determine how much you will save.
