Question

A textbook order was shipped in 3 identical boxes, each containing 8 pounds of books, and a fourth box containing 6 pounds of books. If 15 copies of the same textbook were in the boxes, which expression shows how to determine the weight of each textbook?

(8 × 3 + 6) ÷ 15
or
8 × 3 + 6 ÷ 15
or
(8 × 3) + (6 ÷ 15)
or
8 × (3 + 6) ÷ 15

Answer 1

It's the first one because of PEMDAS. It can't be any of the other ones due to the order of operations.

( 8 x 3 + 6 ) divided by 15
