Answer:
C it was the fastest way to do it when I was in class
So there are 14 books in total you want to do some simple math...
You are given that 8 of the books are new so the rest should be used and you need to figure out the used books so you need to subtract 8 used books from the total amount of books (14)
14-8 =6
So you can safely assume 6 books are used
Now a ratio is one to one so used books to new books
Used books : new books
6 : 8
Now if your told yo simplify then it’s just like simplifying a fraction to get
3 : 4
And now for used books to all books
Used books : all books
6 : 14
Simplified
3 : 7

Answer: 5 friends
Note: if Mariah pays for her own meal, then it would drop to 4 friends.
===========================================================
Explanation:
Add up the amount she earns:
30.25+25.75+11 = 67
Now add up the amounts that she's either in debt or that she spends money on. Ignore the dinner portion for now.
40+2 = 42
She earns $67 total and has to spend $42, without including the dinner portion just yet. That means Mariah has 67-42 = 25 dollars left over.
-------------------
Let x be the number of $5 meals she can buy
So she can spend a total of 5x dollars here. Set this equal to 25 (the amount left over) and solve for x.
5x = 25
x = 25/5
x = 5
She can buy dinner for 5 friends. Or if Mariah is paying for herself as well, then she can buy dinner for 4 friends. It's not clear which scenario your teacher is after, but I'll assume the first scenario.
