Hello,<br>I claim there is a typo in the online version of HtDP:<br>Exercise 4.3.3, the first condition should be <br><pre>[(<span>&lt;=</span> <span>n</span> <span>1000</span>) (<span>*</span> <span>.040</span> n<span></span>)]<br>

<br>instead of<br><br>[(<span>&lt;=</span> <span>n</span> <span>1000</span>) (<span>*</span> <span>.040</span> <span>1000</span>)]<br>
<br>Best regards,<br><br>Jakub Hadam<br></pre>
