3. I must help Johnny buy enough planks for the deck of his tree house. Johnny knows that the planks he buys are 8 feet long and 6 inches wide. The carpenter’s plans will not allow him to use any planks that are less than 3 feet. Even though the planks are 8 feet, Johnny must cut two feet off each board and discard them. 6’2’ next

4. Each plank is 6 inches wide, so I will need two planks per foot. Since the deck must be 6 feet wide, I must multiply 6 by 2. Therefore, Johnny would have to buy 12 planks that are 6 inches wide. Six feet times twelve inches would be seventy-two inches. Therefore, my answer is reasonable. 1’ 6’ next
