Problem 1:
Question:
In order to start constructing the house, Charlie and his father needed to gather some wood from the forest. If they initially have 15 extra planks of wood in the house and Charlie and his father get 10 planks of wood each, how many pieces of wood do they have in total?
Step-by-step Solution:
- Initial planks in the house:
15
- Planks Charlie gets:
10
- Planks father gets:
10
Total planks = Initial + Charlie’s + Father’s
= 15 + 10 + 10
=

Problem 2:
Question:
While building the house, Charlie noticed that they were running out of nails, so he told his father he is going to buy some. If they still have 9 nails left and Charlie bought 2 boxes of nails, the big one containing 35 nails and the small one containing 31, how many nails will they have?
Step-by-step Solution:
- Nails already left:
9
- Nails in big box:
35
- Nails in small box:
31
Total nails = Leftover + Big box + Small box
= 9 + 35 + 31
= 75
✔ Answer: They will have
75 nails in total.

Problem 3:
Question:
To have a more stable treehouse, Charlie’s father decided to tie the corner posts of the house to the tree itself. He used 24 inches of rope for the first post, 20 inches on the second, 14 inches on the third and 12 inches on the fourth. He also had 15 feet of cable but did not use that. How many inches of rope were used?
Step-by-step Solution:
We need to find the total
inches of rope used. The cable (15 feet) was
not used, so we ignore it.
Rope used:
- First post: 24 inches
- Second post: 20 inches
- Third post: 14 inches
- Fourth post: 12 inches
Total rope used = 24 + 20 + 14 + 12
=
70 inches
✔ Answer: 70 inches of rope were used.

✔ Final Answers:
