Question 369897
<br><font face="Tahoma">Let x be the number of people who swam on the third day. <br>

Then we have:<br>

{{{79+(47+x)+x=246}}}<br>

{{{126+2x=246}}}<br>

{{{2x=120}}}<br>

{{{x=60}}}<br>

<b>So it appears 60 people swam on the third day.</b><br>

This means that 107 people swam on the second day.<br>

So 79+107+60 does indeed equal 246, so our math checks out.<br>

I hope this helps!<br>
