Abi paid $55.50 for renting a snowboard starting from 16 00. What would be the latest time she must return the snowboard to the shop?
Amount that Abi 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 Abi paid for
= 8 x
12= 4 h
Total time that Abi paid for
= 1 + 4
= 5 h
5 h after 16 00 = 21 00
Latest time that Abi must return the snowboard to the shop: 21 00
Answer(s): 21 00
