If k is a constant of proportionality then we know from last week that
512= k ·32 so k=512/32=16;
This week
448= k · amount he saved
448=16· amount he saved
amount saved=448/16=28
Answer $28
A histogram is used to show the frequency of data, where the length of the bar represents the frequency.
<em>50 students drank the recommended amount of water.</em>
The recommended amount is given as:

See attachment for histogram.
From the histogram, we have the following observations
- <em>The lengths of all bars of the histogram are less than 48, except one.</em>
- <em>The length of the bar above 48 is 50.</em>
<em />
This means that: 50 students drank the recommended amount of water.
<em>Hence, the number of students is 50</em>
