Yesterday’s Problem
A frog is at the bottom of a
30 foot well. Each day it jumps
up 3 feet but slips back two.
When will he reach the top?
The answer is “day 28” – he jumps
up to 27 feet on day 27, but on day
28 he jumps up 3 feet starting at
27 feet – 27+3=30. At this point
he has reached the top and does
have to slip back two feet.
Today’s Challenge:
Is it legal for a man who lives in the
state of California to marry his widow’s
sister?
