Answer:

$3.79 for an 8 foot board

Step-by-step explanation:

The way to find the answer is calculating the price per foot.

Part 1

$3.79 for an 8 foot board.

one foot would cost:

$3.79 ÷ 8  =  0.47375

Part 2

$6.18 for a 12 foot board?

Price of one foot would be:

$6.18 ÷ 12 = 0.515

$0.47375 is less than $0.515. So, the cheaper treated lumber is the one costing $3.79 for an 8 foot board.
