At a used book sale, Miss Chen bought a box of 20 assorted books for $40. What was the cost per book?(1 point)
0.5 books/$1.00
$0.50/book
2 books/$1.00
$2.00/book
To find the cost per book, divide the total cost of the box of books ($40) by the number of books in the box (20).
$40/20 = $2.00/book
So, the cost per book is $2.00/book.
