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:

$\frac{43.5}{6}=7.25\text{ dollars.}$

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

$7.25\times2=14.50\text{ dollars.}$

Answer: $14.50.
