The number of books the library holds before it received the grant is 17,312 books

Let the original number of books in the library be x

  • If the State Library received a three-year grant to add 69,678 books to their collection, the total number of books will be x + 69,678

  • If during a used book sale, the library sold 430 books, the remaining books will be (x+69,678) - 430 = x + 69,248

If the collection  now is five times more than the original number of books, then;

x + 69,248 = 5x

5x - x = 69,248

4x = 69,248

x = 69,248 /4

x = 17,312

Hence the number of books the library holds before it received the grant is 17,312 books

FromTheMoon [43]

Turn 7 into a fraction so it can be multiplied. > 7/1

Multiply 7/1 by 1/3.

7/1 × 1/3 = 7/3

Simplify 7/3 into a mixed number.

7/3 = 2 1/3

Nolan will need 2 1/3 lbs of turkey.
