Question

can you please coment down below what the answer is and how you got the answer

Answer 1

We know there are 240 nonfiction books. We also know that for every 3 nonfiction books there are 7 fiction books. We can create a table for this.

Nonfiction Fiction

3 7

6 14

9 21

12 28

15 35

18 42

21 49

24 56

We want to know how many total books there are when there are 240 nonfiction books. To do this, multiply the number of fiction books there are when you have 24 nonfiction books (56) by 10. Then, add that number to 240 to get your final answer. I hope this helps!

Answer 2

3x + 7x = 240

10x = 240

x = 24

nonfiction: 3(24)

fiction: 7(24)
