Shannon paid $55.50 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 Shannon paid for all the additional
12 hours
= 55.50 - 11.50
= $44
Number of sets of additional
12 hours
= 44 ÷ 5.50
= 8
Total additional time that Shannon paid for
= 8 x
12= 4 h
Total time that Shannon paid for
= 1 + 4
= 5 h
5 h after 12 00 = 17 00
Latest time that Shannon must return the pair of rollerblades to the shop: 17 00
Answer(s): 17 00
