Question

The book fair had a sale where 6 books were $43.50. If you wanted to buy 2 books, howmuch money would you need?

Answer 1

If 6 books have a cost of $43.50, then each book has a cost of $43.50/6, meaning:

`(43.5)/(6)=7.25\text{ dollars.}`

Therefore if you want to buy 2 books, you would need:

`7.25*2=14.50\text{ dollars.}`

Answer: $14.50.
