Answer:

Diego paid $52 for 12 books.

Step-by-step explanation:

If Mike bought 3 books for $13 that means that a book cost him $ 4.33

$ 13/3 = $ 4.33

And if Diego bought 12 books for the same price, how much did it cost?

An equation called "Rule of 3" is used:

1 book = $ 4.33

12 books = X

The X of the equation is cleared:

X = (12 books * $ 4.33) / 1

X = $ 52 for the 12 books Diego bought.
