But <span style="color:#27ae60;">Sometimes MORE IS BAD</span>. For example, imagine we're sharing a dinner. The more people we have, the less food each person gets. Here's another example:</p>
<p><strong><span style="color:#8e44ad;">Example</span></strong></p>
<p>If a water supply can last $30$ people $12$ days, how long would the water supply last if $40$ people were present? Assume each person drinks the same amount of water each day.</p>
<p><strong><span style="color:#8e44ad;">How do you solve this?</span></strong></p>
<p>The most straightforward way is to set up the following equation:</p>
<p>$$(30)(12) = (40)(time)$$</p>
<p>$$time = \frac{360}{40} = 9 \ days$$</p>
