Question

Sara had 94 dollars to spend on 8 books. After buying them she had 14 dollars. How much did each book cost

Answer 1

Answer: $10

Step-by-step explanation:

Let's analize the information given: We know that  she had $94 to spend on 8 books and after buying these books she had $14. So, we need to calculate the amount of money she spent. Subtract $94 and $14:

$Total\ spent=\ 94-\ 14\\Total\ spent=\ 80$

Then, to calculate the cost of each book, we need to divide the "Total spent" by 8:

$cost\ of\ each\ book=\frac{Total\ spent}{8}\\\\cost\ of\ each\ book=\frac{\ 80}{8}\\\\cost\ of\ each\ book=\ 10$
