Respuesta :
To make at least 2000, 523 books must be sell.
Inequality equation :
Let us consider that, the number of books to be sell is x.
Given that,
To print book, it costs $300 to use the printer plus $3.25 per book.
For x number of books,
[tex]cost=300+3.25x[/tex]
To make at least $2000, cost is greater or equal to 2000.
[tex]300+3.25x\geq 2000\\\\3.25x\geq 1700\\\\x\geq \frac{1700}{3.25}\\ \\x\geq 523[/tex]
Thus, to make at least 2000, 523 books must be sell.
