Abi paid $45.50 for renting a skateboard starting from 15 00. What would be the latest time she must return the skateboard to the shop?
Amount that Abi paid for all the additional
12 hours
= 45.50 - 9.50
= $36
Number of sets of additional
12 hours
= 36 ÷ 4.50
= 8
Total additional time that Abi paid for
= 8 x
12= 4 h
Total time that Abi paid for
= 1 + 4
= 5 h
5 h after 15 00 = 20 00
Latest time that Abi must return the skateboard to the shop: 20 00
Answer(s): 20 00
