Dylan rented 4 books and was charged $9.20. How many days did he rent the books for?
$1 = 100¢
$9.20 = 9.20 x 100 = 920¢
Amount that Dylan paid for each book
= 920 ÷ 4
= 230¢
Amount that Dylan paid for each book for renting for the first 2 days
= 2 x 40
= 80¢
Additional amount that Dylan paid for each book for renting for additional days
= 230 - 80
= 150¢
Number of additional days that Dylan rented for each book
= 150 ÷ 50
= 3
Total number of days that Dylan rented the books
= 2 + 3
= 5
Answer(s): 5
