Answer:
I believe the answer is 10 liters per day
Step-by-step explanation:
When using graphs, you have to look for relationships. This can be found through slopes or simply looking at the graph.
On day 1, you see that the total water consumed is 10. Every single day, the water consumed goes up by 10, seeing as on day 2 there are 20 liters, day 3 there are 30, and so on.
Therefore, the total liters per day is 10.
