Question

Amys class is selling books to raise money for a field trip. If each book sells for $7, how many books will they need to sell to raise $125?

Answer 1

You would start by setting up the equation:

7x=125 where x is equal to the number of books sold

x=17.9

Since you cannot sell .9 of a book, this must be rounded up to 18.
Therefore, Amy must sell 18 books.
