Question

Anna is an avid reader. Her generous grandparents gave her money for

her birthday, and she decided to spend at most on books. "Reading Spot"
is running a special: all paperback books are $8 and all hardback books
are $12. Anna wants to purchase at least 12 books.
X - number of hardback books
y - number of paperback books
Which of the following systems of inequalities correctly represents the
given constraints?
12 + y 150
2 + y 12
12x + 8y > 150
* + y 3 12
O2 + y 150
120 + 8y 2 12
O x + y 2 150
120 + 8y = 12

Answer 1

The anwser is A the first one 8y+12x= 150 and x+y+ 12

Explanation:

First you need the prices to equal how much money she had, im guessing she had 150 because all the anwsers say she did by looking at them. So, that gives you 8y and 12x is less or equal to 150. Then oboulsly the cominded number of books x and why must be at least (greater or equal to) 12 giving x+y is greater or equal to 12
