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:
[tex]Total\ spent=\$94-\$14\\Total\ spent=\$80[/tex]
Then, to calculate the cost of each book, we need to divide the "Total spent" by 8:
[tex]cost\ of\ each\ book=\frac{Total\ spent}{8}\\\\cost\ of\ each\ book=\frac{\$80}{8}\\\\cost\ of\ each\ book=\$10[/tex]
