Part 1:"The students in art class are designing a stained-glass window to hang in the school entryway. The window will be 3 feet tall and 4 feet wide. They have raised $100 for the project. The colored glass costs $5 per square foot and the clear glass costs $2 per square foot. The material they need to join the pieces of glass together costs 10 cents per foot and the frame around the window costs $4 per foot.
Do they have enough money to cover the cost of making the window?" (PART 1 IS DONE)


Part 2:"A local community member sees the school’s stained glass window and really likes the design. They ask the students to create a larger copy of the window using a scale factor of 3 (9 feet tall and 12 feet wide). Would $450 be enough to buy the materials for the larger window?"

Part 3:"Make your own stained glass window design that could be made for less than $450. Show your thinking."
