To determine which house had the lowest cost per day, we need to find the cost per day for House 1 based on the provided table.
From the table:
- For 6 days, the cost is $97.50, which gives a cost per day of \( \frac{97.50}{6} = 16.25 \) dollars per day.
- For 8 days, the cost is $130.00, which gives a cost per day of \( \frac{130.00}{8} = 16.25 \) dollars per day.
- For 12 days, the cost is $195.00, which gives a cost per day of \( \frac{195.00}{12} = 16.25 \) dollars per day.
The cost per day for House 1 is consistently $16.25.
Now, we need to compare this with the represented graph for House 2. Since we don't have the graph, we would typically analyze it to find the cost per day for House 2. Assuming the graph's data is accessible and you can observe the costs, derive the daily cost in a similar manner.
If House 2's cost per day is greater than $16.25, then House 1 is cheaper, and vice versa.
If, for example, the cost per day for House 2 is less than $16.25, then House 2 would be cheaper.
Based on the information you provided, if you have the graph and determine that House 2 has higher costs, then:
House 1 had the lowest accumulated electricity cost per day, so you would enter 1.
If the graph shows that House 2's cost per day is less than $16.25, then you would enter 2.
In summary, check the graph to see the cost for House 2 and compare; based on that, select the appropriate answer.
