Lizzy: Tommy has a flag that is 5 feet wide and 4 feet tall. He wants to paint it with a new design. He knows from experience that he needs to paint both sides. Paint costs $2 a quart and a quart is good for 4 square feet. How much does he spend on paint?.
Me: Hmmm, let me think. I think this is the detailed solution:

Each side of the flag is 20 square feet because 5 x 4 = 20. Both side total to 40 square feet because 2 x 20 = 40. He will need 10 quarts because 40 / 4 = 10. This will cost $20 because 10 x 2 = 20. Final answer: 20.
