Hello Savannah. In order to answer this question, you have to understand that unit price is the price per book. In order to find the lower unit price, we must find the price per book in store and online. Then we can compare the unit prices in store and online to find the lower unit price. We know that in store, the price for 6 books is $32.75. We can set up a ratio to show this relationship:
$32.75/6 books
To find the price per book, we can divide the total price for 6 books by the number of books (6 books).
$32.75/ 6 books = $5.46 per book
We can now set up a ratio to find the price per book online.
$32.16/ 6 books
Now we can find the price per book by dividing the total price for 6 books by the number of books (6 books).
$32.16/ 6 books = $5.36 per book
We can now compare the prices to see which one is the lower price.
$5.36 per book online < $5.46 per book in store
The online price of $5.36 per book is the lower unit price.
To finally answer your question, the place with the lower unit price is online.
