Edward buys a novel for $8.40 and a bookmark for $1.20 from a bookstore. The store is having a sale, and everything is 35% off! How much does Edward pay for both items ( not including tax )?

Answers

Let's start with calculating the $8.40 novel with the 35% off.

First, we need to convert the percentage (35%) into a decimal. We can do this by dividing the percentage over 100.

35/100 = 0.35

Now, our next step is to find 0.35% of $8.40 (original price of the novel). To do this, you need to multiply the percentage by the original price.

0.35% × $8.40 = 2.94

What we recently received (2.94), is the amount of money that we are saving from the sale. The original price of the novel was $8.40, and with the 35% off, we are saving $2.94 on it.

Our last step is to subtract the original price and the sale.

$8.40 - $2.94 = $5.46

Now - we know that our new cost just for the novel is $5.46.

------

Moving on to the bookmark which costs $1.20, we can start by taking our percentage from last time (0.35) and instantly start multiplying just like we did on the novel.

0.35% × $1.20 = $0.42

So, with the 35% discount, you are saving $0.42 on the bookmark. Let's subtract and find the total amount Edward is having to pay now.

$1.20 - $0.42 = $0.78

He will purchase the bookmark for only $0.78.

-----------

Our final step is to add both the novel and bookmark up to find the total price overall.

$5.46 + $0.78 = $6.24

Edward will have to pay $6.24 for both the novel and bookmark.

$8.40*0.65(the new price 65% of the original price that Edward needs to pay)=$5.46 $1.20*0.65=$0.78 5.46+0.78=$6.24
