Problem 2
Kim has a small container and a large container as shown.
[IMG]
It takes 16 of the small containers to fill the large container. Three small containers leave 1.95 gallons of space in the big container.
What is the size of each of the two containers?


Concept/skill: 
Analyze and solve pairs of simultaneous linear equations.

Answer: 
Yes. The last three rows of the table in the first problem involves solving pairs of simultaneous linear equations. The second word problem can also be represented as two simultaneous linear equations.

problem_activity: Problem 1
A carpenter is building a new wall for a house that he is renovating. He knows that there will be a door and a window in the wall. Around the door and window, he uses wooden board to create the wall. A blueprint of the wall is shown below.
[IMG]
How much wooden board, in square feet, does the carpenter need to build the wall?
Problem 2
Jamie is planning to cover a wall with red wallpaper. The dimensions of the wall are shown below.
[IMG]
a.   How many square feet of wallpaper are required to cover the wall?
b.   Wallpaper comes in long rectangular strips that are 24 inches wide. If Jamie lays the strips of wallpaper vertically, how many strips will she use and how long will each strip be? Explain.
c.   If Jamie lays the strips of wallpaper horizontally, can she cover the wall without wasting any wallpaper? Explain.
