Bryan brought his series set of Rowan and the Dragon Quest to a secondhand store to sell. He was paid cash for all 5 books in the set. Before he left, Bryan used $29.75 of his earnings to purchase a used e-reader. He had $2.75 remaining. What was the value of each book in the set?

Let's denote the total amount of money Bryan received for selling all 5 books as $ T $. We know:

- Bryan spent $29.75 on the e-reader.
- He had $2.75 left after buying the e-reader.

Thus, the total amount of money Bryan had after selling the books is:
\[
T = 29.75 + 2.75 = 32.50
\]
Now, since Bryan sold 5 books and earned $32.50 in total, the value of each book is:
\[
\text{Value per book} = \frac{32.50}{5} = 6.50
\]

So, each book was worth **$6.50**.

2. What would be the total if Bryan spent only $20 on the e-reader?
3. How much would each book be worth if Bryan received $50 for all 5 books?
4. If Bryan sold 3 books for $19.50, how much did he make per book?
5. How much more would Bryan need if the e-reader cost $35?

**Tip**: When dividing a total evenly among a number of items, ensure all parts sum back to the original total to check your work.
