<p>Does anyone know where in the textbook an online access code would be for MAC1140? Or how I get one/how expensive they are/if I really need it? Thanks!</p>
<p>I have no experience with the specific book you are using, but every textbook online access code I’ve ever seen comes on a separate card that is included with the book when it is bought new. It’s meant to be disposable/one use only, most people throw them away after using the code to register. </p>
<p>You can usually buy access by going to the publisher’s website for the book.</p>
<p>Yeah, I bought the book used. Thanks!</p>
