Flynn rented 4 books and was charged $26.40. How many days did he rent the books for?
$1 = 100¢
$26.40 = 26.40 x 100 = 2640¢
Amount that Flynn paid for each book
= 2640 ÷ 4
= 660¢
Amount that Flynn paid for each book for renting for the first 6 days
= 6 x 50
= 300¢
Additional amount that Flynn paid for each book for renting for additional days
= 660 - 300
= 360¢
Number of additional days that Flynn rented for each book
= 360 ÷ 60
= 6
Total number of days that Flynn rented the books
= 6 + 6
= 12
Answer(s): 12
