Ex # 1: A company charges $2 for each balloon in an arrangement and a $3 delivery fee. You have $9 to spend. How many balloons can you purchase?

3. Ex # 1 set up Let x represent # of balloons
Words: (cost of 1 balloon) ( times) (# of balloons) (plus) (cost of delivery) (equals) (total spent)
$ * x $ = $ 9
2.00x + 3 = 9
- 3 = - 3
2.00x = 6
x = 3 (You can purchase 3 balloons)

Ex # 2: Tonia had her birthday party at the movies. It cost $27 for pizza and $8.50 per friend for the movie tickets. How many friends did Tonia have at her party if she spent a total of $78.

5. Ex # 2 set up Let x represent # of friends
Words: (cost of 1 friend) ( times) (# of friends) (plus) (cost of pizza) (equals) (total spent)
$ * x $ = $ 78
8.50x = 78
- 27 = - 27
8.50x = 51
x = 6 (Toya can have 6 friends at her party)
