Fred went to a hardware store in Boston with Alex, Ben, and George. He noted that a hammer cost ten times as much as a screwdriver, and a power saw cost ten times as much as a hammer. The storekeeper said that Ben could buy a power saw, George could buy a screwdriver and Alex could buy a hammer. Based on this, what would the storekeeper let Fred buy?
Fred could buy all three (the power saw, hammer and screwdriver) since he had $111 with him (a $1 bill-George Washington, a $10 bill-Alexander Hamilton, and a $100 bill-Ben Franklin). Boston is in the USA and therefore uses the US currency I just described.
