A bookcase in the library has 3 shelves. The bottom shelf can hold 12 books. Each of the other shelves has 6 more books than the shelf below it. How many total books are on the bookcase?
We can work backwards. Bottom shelf = 12 books. 12 + 6 = 18, so the 2nd shelf has 18 books. 18 + 6 = 24, so the 1st or top shelf has 24 books. We can find our answer if we add the total amount of books on each shelf together. 12 + 18 + 24 = 54 books.
