Question 1208713
<br>
In the work you show, you started with x for what the bookstore paid for the book.  That's a good start, since it is what the problem asks you to find.<br>
With the 35% markup, the expression 0.35x represents the AMOUNT of the markup.<br>
Your equation is<br>
0.35x = 92.00<br>
But 0.35x is only the amount of the markup.  The $92 price of the book is what the bookstore paid for the book, PLUS the 35% markup:<br>
x + 0.35x = 92.00<br>
Similar to the problem I helped you with a while ago, you will be better with setting up the equation correctly if you write out more of your work.  In the work you show, you start with this:<br>
Let x = money the store paid for the book.
The store sold the book for $92 after marking up the price they paid for the book by 35%.<br>
Then you start guessing -- ending up trying to write your equation using only the "$92" and the "35%".  That's primarily because your second sentence doesn't give you a clear idea of what the equation needs to say.<br>
Using your basic ideas and writing things out in more detail, a better start on the problem might have been something like this:<br>
Let x = money the store paid for the book
Then 0.35X is the amount of the markup, because the store marked up the price by 35%<br>
Then, instead of your next sentence, change the wording to say more exactly what you want it to say:<br>
The store sold the book for $92, which is what it paid for the book plus the 35% markup.<br>
By changing the wording of that sentence, it becomes more clear that the equation needs to say that the price of the book is the sum of two things -- what the store paid for the book and the amount of markup.<br>
