Which of the following is the most cost-effective rate for lumber?

Explanation:
The key idea is price per board foot. To compare these deals, divide the total price by the number of board feet to get the cost per unit. - 24 board feet for $15 → 15 ÷ 24 = $0.625 per board foot - 50 board feet for $25 → 25 ÷ 50 = $0.50 per board foot - 36 board feet for $13.68 → 13.68 ÷ 36 = $0.38 per board foot - 12 board feet for $6.50 → 6.50 ÷ 12 ≈ $0.542 per board foot The cheapest per-board-foot rate is $0.38, so the option with 36 board feet for $13.68 is the most cost-effective.

The key idea is price per board foot. To compare these deals, divide the total price by the number of board feet to get the cost per unit.

  • 24 board feet for $15 → 15 ÷ 24 = $0.625 per board foot

  • 50 board feet for $25 → 25 ÷ 50 = $0.50 per board foot

  • 36 board feet for $13.68 → 13.68 ÷ 36 = $0.38 per board foot

  • 12 board feet for $6.50 → 6.50 ÷ 12 ≈ $0.542 per board foot

The cheapest per-board-foot rate is $0.38, so the option with 36 board feet for $13.68 is the most cost-effective.
