A certain library assesses fines for overdue books as follows. On the first day that a book is overdue, the total fine is $0.20. For each additional day that the book is overdue, the total fine is either increased by $0.30 or doubled, whichever results in the lesser amount. What is the total for a book on the third day it is overdue?
Pick:  A) $0.60  B) $0.70  C) $0.80  D) $0.90  E) $1.00
1st day fine - 0.2   2nd day fine - 0.2*2 = 0.4 (as doubling gives lower value)   3rd day fine - 0.4+3 = 0.7 (as doubling gives higher value)   Answer: $0.70.
