algebraically disinclinded

<p>Can you help me please?</p>

<p>I don't get how to algebraically think about this one. Thanks in advance! :-D</p>

<p>A club is buying boxes of candy bars to sell for a fundraiser. If each box contains c candy bars, and each member sells x bars each day, how many boxes are needed to supply enough candy bares for 3c members to sell for 5 days?</p>

<p>Also, how should I think of these problems because I have trouble interpreting what to do.</p>

<p>Thanks!</p>
