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.
