Jason checked his gift wrap supply and found he only had a small piece of wrapping paper left. He knows that Lila loves to unwrap the boxes separately. He is afraid it might take more paper to wrap each box individually than to wrap the two boxes together in one package. He asks for you advice. How could you help?

7. Challenge Problem: You finish painting the walls in your bedroom and find you have 1 quart of paint leftover. The label says that 1 gallon of paint will cover 20m squared. You measure an unpainted cinder block wall on your basement and find that its 5 m squared. Because you know there are 4 quarts in a gallon, you decide you have enough paint to cover the wall. Unfortunately, you run out of paint when only 90% of the cinder block wall has been painted. Explain, in terms of this lesson, why you did not have enough paint.
