Fabian rented 3 books and was charged $19.50. How many days did he rent the books for?
$1 = 100¢
$19.50 = 19.50 x 100 = 1950¢
Amount that Fabian paid for each book
= 1950 ÷ 3
= 650¢
Amount that Fabian paid for each book for renting for the first 6 days
= 6 x 50
= 300¢
Additional amount that Fabian paid for each book for renting for additional days
= 650 - 300
= 350¢
Number of additional days that Fabian rented for each book
= 350 ÷ 70
= 5
Total number of days that Fabian rented the books
= 6 + 5
= 11
Answer(s): 11
