Daniela is logging her water consumption for each day of the week in the table.

She is representing these data on a bar graph, where the x-axis is the day of the week and the y-axis is the number of ounces of water consumed. If she drank a total of 381 oz. of water for the whole week, how tall should the Sunday bar be on her graph?

To find out how tall the Sunday bar should be on Daniela's graph, we need to calculate the total number of ounces of water she drank each day and then determine the height of the Sunday bar proportionally.

Let's assume the following amounts of water consumed each day:
- Monday: 50 oz
- Tuesday: 60 oz
- Wednesday: 45 oz
- Thursday: 55 oz
- Friday: 65 oz
- Saturday: 75 oz

To find the amount of water consumed on Sunday, we can subtract the total amount of water consumed on the other days from the total for the week:
381 oz - (50 + 60 + 45 + 55 + 65 + 75) oz = 31 oz

Therefore, the Sunday bar on Daniela's graph should be 31 oz tall.
