The top shape (A) is made from four polygons. The bottom shape (B) has the original four polygons and one extra square (with an area of 1). How can the area of Shape A and Shape B have different areas if we only rearranged the pieces.

A Day at the Fairs
The problem this week is an old one, in fact over 500 years old. It goes back to the days in Europe when fairs were common in many cities, and merchants would travel from city to city, selling their various goods and buying other items they desired.
It seems that a humble merchant visited three fairs. At the first fair, early in the morning, he doubled his money selling his products, but spent $30 in food and buying other items. (Note:to make things easier to write, we will use the dollar sign for the unit of money.)

At midday at the second fair, he tripled his money and spent $54. At the third fair in the afternoon he quadrupled his money but spent $72.
Upon his return home to his wife and ten children, late that day, he counted the money he had in his bag; there was $48.
Did the man return richer or poorer than when he left? And how much did the man gain or lose, respectively?
Extra:If you did your work straightforwardly, your next-to-last step of equation work was of the form Ax = B. The number B is in some way rather interesting; what is it?

Suppose we get a rope that's about 40,000 kilometers long, and tie it snug around the Earth's equator (imagine a perfectly spherical and solid earth). Now let's add just 10 meters of slack to the rope and distribute it around the planet so that the rope is equidistant from the surface at all points (vertically).
How much space is between the rope and the Earth's surface? Before solving numerically, take a ballpark guess - can you fit a mountain under the rope? Walk underneath it? Can you even slide a sheet of paper between the rope and the Earth's surface?
