Question

You pay for a fiction book, a nonfiction book, and a bookmark with three $5 bills. The fiction book costs $5.43. The nonfiction book costs $3.89. Your change is $3.45. How much does the bookmark cost?

Answer 1

The bookmark costed 2.23

We have 3 $5
3 x 5 = 15

Now, we add the cost for both of the books and our remaining change
5.43 + 3.89 + 3.45 = 12.77

And then we subtract to 15
15 - 12.77 = 2.23

We can also check our answer by adding the costs of the bookmark and both books and subtracting it to 15
4.43 + 3.89 + 2.23 = 11.55
15 - 11.55 = 3.45

Answer 2

2.23

Explanation:

You have 3 $5 bills which us 15 dollars. 15 dollars - 5.43 - 3.89 - 3.45 = 2.23 dollars for the bookmark.

To see if you are correct, you can add 3.45, 2.23, 3.89, and 5.43 to get your answer.
