bellringer - 2.2.11

19. How might you construct a petty cash fund for your own personal use at home?



20. If the world were overrun by groundhogs--for they've been busy scheming while bunkered down in their holes for the many years of long winters--might they look do away with the study of meteorology and replace it with the reading of their own shadows in order to predict the coming of spring and other weather related events? Can you come up with a similar abortive system for controlling cash flow?
