MAML Olympiad

<p>Anybody taking this tomorrow?</p>

<p>I think it's PAML here, but yes.</p>

<p>my teacher gave my class a practice test and I'm not sure how to answer this one question</p>

<p>This morning, five hundred dollars was deposited into a bank account that pays no interest. Every 3rd day after today, $12 is withdrawn. Every 17th day after today, $25 is withdrawn. Every 51st day after today, $100 is deposited. How many days after today will the account have a negative balance?</p>

<p>a)131 b) 132 c) 133 d)134 e) 135</p>

<p>Is there some equation you can draw from this problem? I'm not sure how to do it. Thanks for any help</p>
