Helen has 80 books to sell. each book is fiction or non-fiction. the ratio of the number of fiction books to the number of non-fiction books is 3: 1. each book has a normal price of £10. helen reduces the price of all the non-fiction books. [non-fiction. all books 1/2 price] helen sells all 80 books. work out the total amount of money helen will recieve.

If all my calculations are correct Helen should make £700. If she has a 3:1 ratio that means she has 3 times as many fiction books as she does nonfiction. This means out of Helens total 80 books, 60 would be fiction and 20 would be nonfiction. Now to calculate the price, all the fiction books are £10 so that would give her £600. All the non fiction books are £5 and so that would give her £100 and then combined Helen should have £700
