Natalie paid $33 for renting a pair of rollerblades starting from 12 00. What would be the latest time she must return the pair of rollerblades to the shop?
Amount that Natalie paid for all the additional
12 hours
= 33 - 8.50
= $24.50
Number of sets of additional
12 hours
= 24.50 ÷ 3.50
= 7
Total additional time that Natalie paid for
= 7 x
12= 3
12 h
Total time that Natalie paid for
= 1 + 3
12= 4
12 h

12 h after 12 00 = 16 30
Latest time that Natalie must return the pair of rollerblades to the shop: 16 30
Answer(s): 16 30
