Marco purchased a large box of comic books for $300. He gave 15 of the comic books to his brother and then sold the rest on an internet website for $330 making a profit , making a profit of $1.50 on each one. how many comic books were in the box? what was the original price of each comic book (assuming they all cost the same amount)?

There are 75 books.

Profit = selling price - cost price

Number of books cannot be negative.

So, there are 75 books.

Price of each book =
