It takes 40 ink cartridges and 200 pages to print a book, and it takes 303030 ink cartridges and 80 pages to print a magazine. Sarah wants to print books and magazines with at most 300 ink cartridges and 1200 pages. Let B denote the number of books she prints and M the number of magazines she prints.

The inequalities equations are as follows

Step-by-step explanation:

The inequality function is as follows:

Here we assume the book be B

And, the magazine be M

Given that 40 cartridges per book  and 30 cartridges per magazine would be taken and at most 300 cartridges is used

So, the equation would be

40B +30M ≤ 300

Now

There are 200 pages for printing a book and for magazine there is 80 pages and at most 1,200 pages is used

So, the equation is

200B +80M ≤ 1200

answer: a.

step-by-step explanation: the answer is a. because, you need to converge the fractions to find a solution.
