Acertain library assesses fines for overdue books as follows. on the first day that a book is overdue, the total fine is $0.10. 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 fine for a book on the fourth day it is overdue?
a. $0.60b. $0.70c. $0.80d. $0.90e. $1.00

Option B. $0.70

Step-by-step explanation:

First day fine = $0.10

Second day fine (doubled or $0.30 which is lesser)

= $0.10 + $0.10           [$0.10 is lesser than $0.30]

= $0.20

Third day fine = $0.20 + $0.20           [ $0.20 is lesser than $0.30]

                      = $0.40

Fourth day fine = $0.40 + $0.30  = $0.70

[$0.30 is cheaper than doubling the amount $0.40 + $0.40]

Therefore, the total fine for a book on the fourth day is $0.70

the circle one
