Bryan took a look at his books and magazines. If he has 9 books and 46 magazines in each of his 10 bookshelves how many magazines does he have in total?
Bryan has 9 books and 46 magazines in each of his 10 bookshelves.

Let's introduce the following variables:

x = the number of bookshelves
y = the number of books
z = the number of magazines

We know that:

x = 10
y = 9
z = 46

Now we can write an equation:

x * y * z = 10 * 9 * 46

x * y * z = 4140

Therefore, Bryan has 4140 magazines in total.
