Which is the better deal? 4 notebooks for $15 or 6 notebooks for $21?

6 books for $21

Step-by-step explanation:

In order to find the better deal you need to know what the cost is for 1 book corresponding to each deal, you do this by dividing the cost of the books by the total amount of books.

21/6 = $3.5

15/4 = $3.75

You can get books for a better deal by buying 6 books for $21

So first we are going to divide,

then we compare and see which is the lower price

15 divided by 4 = 3.75

21 divided by 6 = 3.5

4 books for 15 dollars is better I hoped i did the division right .
