House 1
To determine which house had the lowest cost per day, we need to compare the values in the table and the graph.
Looking at the table, we can see that House 1 has electricity costs of $97.50 for 6 days, $130.00 for 8 days, and $195.00 for 12 days.
Looking at the graph for House 2, we can see that the coordinates of the plotted points connect to form a line. The line passes through the points (0,0), (5,75), (10,150), (15,225), (20,300), (25,375), and (30,450).
Comparing the values, we can see that House 1 has a higher cost per day compared to House 2. Therefore, House 2 had the lowest cost per day.
To answer the question, enter 2 for House 2.
