Suppose that two newly born rabbits, one male,one female, are put in a field. Beginning in their second month, a pair of rabbits can produce another pair of rabbits (a male and a female) every month thereafter.Assuming that rabbits never die, how many pairs of rabbits will there be after n months?

Three guests checked in at ahotel and paid $30 for their room. A while later, the deskclerk realized that the room should have cost only $25, soshe gave the bellboy $5 to return to the three guests. Thebellboy realized that $5 couldn't be divided evenly amongthe three guests so he kept $2 and gave $1 to each of theguests. It seems that the three guests have now each spent$9 for the room (that makes $27) and the bell boy has $2,for a total of $29. Where is the missing dollar?
