Answer
The correct equation is \( 4.50b = 18 \).
Solution
James spends 4.50 dollars on each book, and if he buys b books, the total cost would be 4.50 × b. Since he has 18 dollars, the equation representing the situation is:
4.50b = 18
So, the correct answer is option b.

Simplify this solution Beyond the Answer
To determine how many books James can buy with his budget of $18, we need to consider the cost per book, which is $4.50. The equation that represents the relationship between the total amount James has, the number of books he can buy, and the cost per book is \( 4.50b = 18 \). Here, \( b \) represents the number of books that James can purchase. Now, if he were to buy more than 4 books, his total cost would exceed $18, leading to a fun scenario where he might have to start negotiating with the bookstore or opt for a used book section! So, stick to the affordable limit to keep your wallet intact!
