Linda paid $36.50 for renting a pair of rollerblades starting from 16 00. What would be the latest time she must return the pair of rollerblades to the shop?
Amount that Linda paid for all the additional
12 hours
= 36.50 - 9.50
= $27
Number of sets of additional
12 hours
= 27 ÷ 4.50
= 6
Total additional time that Linda paid for
= 6 x
12= 3 h
Total time that Linda paid for
= 1 + 3
= 4 h
4 h after 16 00 = 20 00
Latest time that Linda must return the pair of rollerblades to the shop: 20 00
Answer(s): 20 00
