Question
Pizzazz Publications is having some books printed. The printer charges $800 plus $5 per book. What equation could help me find how many books can be printed for $4,000?
800 + 5x = 4000
800 + 5 = 4000
4000 = 800 + 5
4000 + 5х= 800
800x + 5 = 4000
800 + 5x = 4000
800 + 5 = 4000
4000 = 800 + 5
4000 + 5х= 800
800x + 5 = 4000

To find how many books can be printed for $4,000, you need to use an equation that correctly represents the total cost based on the given pricing structure.
The cost structure is:
- A fixed charge of $800.
- A variable charge of $5 per book, which we'll represent as \( x \) (the number of books).
The correct equation is:
\[ 800 + 5x = 4000 \]
So the first option you provided is the correct equation to solve for \( x \) (the number of books). The other options are not correct formulations for this scenario.
To find the number of books, you would solve the equation:
1. Subtract $800 from both sides:
\[ 5x = 4000 - 800 \]
\[ 5x = 3200 \]
2. Divide by 5:
\[ x = \frac{3200}{5} \]
\[ x = 640 \]
Thus, Pizzazz Publications can print **640 books** for $4,000.
