The text is in English, so here is the response:

1. Household items consumed frequently: These can vary depending on the household, but common items include food items like bread, milk, eggs, fruits, vegetables, and pantry staples like rice, pasta, and canned goods. Non-food items might include toilet paper, cleaning supplies, and personal care items like shampoo and soap. These items are consumed frequently because they are essential for daily living.

2. Tracking consumption: You could keep receipts from grocery shopping, make a note of when items are used up, or even keep a diary of meals and other uses of these items.

3. Decision-making: Usually, the person who does the shopping or the person who manages the household budget would have this information.

4. Recording and maintaining data: You could use a spreadsheet or a notebook to record the data. Make sure to update it regularly and keep it in a safe place.

5. Applicable concepts: Concepts from economics like supply and demand, price elasticity, and consumer behavior could be applicable.

6. Representing data: You could use graphs, charts, or infographics to represent the data. This could help you identify patterns or trends in the data.

7. Possible obstacles: Some possible obstacles could include not having access to all the necessary information, difficulty in tracking all the items, or changes in consumption patterns due to unforeseen circumstances.

8. Discussing with teacher: If you have any doubts or need further guidance, you should definitely discuss your plan with your teacher. They can provide valuable feedback and help you refine your plan.
