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

Explanation:

Step1: Calculate total weight

3 boxes with 8 pounds each: \(8\times3\). Add 6 pounds from the fourth box: \(8\times3 + 6\).

Step2: Divide by number of textbooks

Total weight divided by 15 copies: \((8\times3 + 6)\div15\).

Answer:

\((8 \times 3 + 6) \div 15\)
