Question

Monday 64 oz.
Tuesday 50 oz.
Wednesday 60 oz.
Thursday 54 oz.
Friday 39 oz.
Saturday 66 oz.
Sunday
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?

Answer 1

To find out how tall the Sunday bar should be on Daniela's graph, we first need to determine how much water she drank on Sunday based on the total water consumption for the week.

First, we sum the water consumed from Monday to Saturday:

- Monday: 64 oz.
- Tuesday: 50 oz.
- Wednesday: 60 oz.
- Thursday: 54 oz.
- Friday: 39 oz.
- Saturday: 66 oz.

Now, we calculate the total water consumed from Monday to Saturday:

\[
64 + 50 + 60 + 54 + 39 + 66
\]

Calculating step by step:

1. \( 64 + 50 = 114 \)
2. \( 114 + 60 = 174 \)
3. \( 174 + 54 = 228 \)
4. \( 228 + 39 = 267 \)
5. \( 267 + 66 = 333 \)

So, the total water consumed from Monday to Saturday is 333 oz.

Now, we know that the total amount of water consumed for the whole week is 381 oz. Therefore, we can find out how much water she drank on Sunday:

\[
\text{Sunday's consumption} = \text{Total weekly consumption} - \text{Total from Monday to Saturday}
\]

Substituting the values:

\[
\text{Sunday's consumption} = 381 - 333 = 48 \text{ oz.}
\]

So, the bar for Sunday on Daniela's graph should be 48 oz tall.
